Introduction
As the global energy transition converges with the rapid expansion of the digital economy, power systems are accelerating toward greater efficiency, intelligence, and flexibility. As the core component of power transmission and conversion, transformers are becoming a critical focal point for technological innovation and high-quality industry development.
Conventional transformers, built on the principle of electromagnetic induction, have long supported the operation of modern power grids. However, with the rise of renewable energy integration, explosive AI computing demand, and smart grid deployment, their limitations—including bulky size, rigid architecture, and limited functionality—are becoming increasingly evident.
Driven by next-generation power semiconductor technologies, Solid-State Transformers (SSTs) are emerging as a disruptive upgrade and a key interface connecting modern power systems with diversified end-use applications. According to reports from authoritative research institutions including GGII, the global SST market was valued at approximately USD 1.5 billion in 2025 and is projected to reach USD 12 billion by 2030, representing a compound annual growth rate (CAGR) of over 35% from 2025 to 2030. China is expected to lead global market growth, with its SST market reaching approximately RMB 4.2 billion in 2025, up 38.2% year-over-year. CCID Consulting further forecasts that China’s SST market will maintain a CAGR exceeding 40% between 2025 and 2030, surpassing RMB 35 billion by 2030 and becoming the world’s largest single SST market.
Enabled by advanced power semiconductor technologies, SSTs are redefining power conversion architectures and becoming essential equipment for future energy infrastructure and intelligent electrical loads. With deep expertise in magnetic sensing and control IC technologies, Giant Magnet Intelligent remains closely aligned with the forefront of the power industry. This article analyzes the current status and future trends of the SST industry from four dimensions—technology comparison, industrial chain, application scenarios, and domestic enterprise landscape—while highlighting the core value of Giant Magnet Intelligent in this evolving ecosystem.
I. The Final 100 Meters: The Evolutionary Battle Between Conventional and Solid-State Transformers
In the “last 100 meters” of the power network—from distribution rooms to server racks, from energy storage containers to EV charging stations—traditional transformers are facing unprecedented challenges. Their bulky structure and inflexible architecture not only consume increasingly valuable urban space, but also struggle to handle the rapidly fluctuating loads driven by AI computing infrastructure. Today, the rapid rise of Solid-State Transformers is reshaping this landscape.
A Solid-State Transformer, also known as a Power Electronic Transformer (PET), is a next-generation power conversion device built on advanced power electronics, high-frequency conversion technologies, and intelligent control systems. Its core functions include voltage conversion, bidirectional power flow, and power quality management. Compared with conventional transformers, SSTs fundamentally represent a technological shift from “electromagnetic induction” to “power electronics-based conversion.”
To fully understand the value of SST technology, it is essential to first clarify the core technical differences between SSTs and conventional transformers, while objectively evaluating the strengths and limitations of each. This helps define the practical application boundaries and long-term development potential of SSTs.
1.1 Differences in Core Technical Principles
1.2 Comprehensive Comparison Across Key Dimensions
From the four critical dimensions of performance, size, functionality, and maintenance, the differences between conventional transformers and SSTs become clear, highlighting the core advantages of SST technology:
1.3 Summary of Advantages, Limitations, and Application Boundaries
Core Advantages of SSTs
- Higher energy efficiency and lower power losses
- Compact size and lighter weight
- Integrated multifunctional capabilities
- Simplified operation and maintenance
- Fast dynamic response
These advantages align closely with global carbon reduction goals and the requirements of next-generation power systems.
Current Limitations of SSTs
- Higher initial investment cost
- Significant technical complexity
- Greater thermal management challenges
- Incomplete industry standards and certification systems
Rather than being direct replacements, conventional transformers and SSTs will coexist for the foreseeable future. Conventional transformers still maintain cost advantages in large-scale bulk power transmission applications, while SSTs are becoming irreplaceable in emerging high-performance scenarios and are expected to gradually move toward mainstream adoption.
II. SST Core System Design and Topology Architecture Analysis
This section focuses on the system-level design of Solid-State Transformers (SSTs), including mainstream topology architectures and optimization strategies for critical functional stages, providing a comprehensive overview of the technical foundation behind SST technology.
2.1 Mainstream SST Topology Architectures and Hierarchical Design
Depending on application voltage and power levels, SST topologies are generally divided into single-phase and three-phase architectures. Among them, three-phase topologies are primarily used in medium- and high-voltage, high-power applications such as power grids, renewable energy systems, and data centers, making them the current focus of industry R&D and commercialization.
Input-Stage Topology Design
In medium- and high-voltage applications, the input stage mainly adopts either Cascaded H-Bridge (CHB) or Modular Multilevel Converter (MMC) topologies.
Cascaded H-Bridge (CHB) Topology
The CHB topology features a relatively simple structure, high modularity, and lower control complexity. It is currently the mainstream solution in commercially deployed SST products in China. It is well suited for 10 kV distribution network applications and allows flexible adaptation to different voltage levels through modular cascading.
Modular Multilevel Converter (MMC) Topology
The MMC topology provides superior output waveform quality and lower harmonic distortion, making it highly suitable for 35 kV and higher-voltage applications. It offers significant advantages in ultra-high-voltage flexible DC transmission systems and large-scale renewable energy integration. However, it also requires more sophisticated control algorithms.
Isolation-Stage Topology Design
The isolation stage is the core of SST technology for achieving high-frequency isolation and efficient energy transfer, and it is also the primary focus of topology optimization.
The industry mainly adopts the Dual Active Bridge (DAB) topology and its optimized resonant derivatives, including:
- Series Resonant Converter (SRC)
- LLC Resonant Converter
These topologies can be flexibly selected according to specific operating conditions and system requirements.
Output-Stage Topology Design
The output stage can generally be categorized into two types based on load requirements:
Three-Phase Full-Bridge Inverter Topology for AC Loads
This topology delivers stable utility-frequency AC output while also supporting reactive power compensation and harmonic mitigation.
DC/DC Buck-Boost Topology for DC Loads
This topology provides stable DC voltage output and is widely used in:
- Data centers
- DC fast charging stations
- Energy storage systems
It is currently one of the fastest-growing SST application segments.
2.2 Optimization of Core Isolation-Stage Topologies: DAB vs. SRC
The choice of isolation-stage topology directly determines SST system efficiency, power density, and operational stability. Currently, the two most representative solutions are the DAB topology and the SRC topology.
Dual Active Bridge (DAB) Topology
The DAB topology is the classical solution for SST isolation stages. It consists of full-bridge circuits on both sides of a high-frequency transformer, enabling bidirectional power transfer.
Key advantages include:
- Simple control logic
- Fast dynamic response
- Excellent suitability for bidirectional energy flow applications
Its core feature is Zero Voltage Switching (ZVS) during turn-on operations for all switching devices. However, because switches turn off at peak current conditions, tail currents generate relatively high turn-off losses, particularly under light-load conditions where efficiency drops become more noticeable.
Series Resonant Converter (SRC) Topology
The SRC topology introduces a resonant tank based on the DAB architecture, enabling both:
- Zero Voltage Switching (ZVS)
- Zero Current Switching (ZCS)
This fundamentally eliminates turn-off losses in switching devices. Compared with DAB, overall system efficiency can improve by approximately 0.5%–1%, delivering superior efficiency under rated operating conditions.
However, the resonant behavior also increases peak current levels, which raises conduction losses. As a result, SRC topologies are generally less adaptable than DAB under wide load fluctuation conditions.
Comparative Summary
Overall:
- DAB topologies are better suited for renewable energy and energy storage applications involving bidirectional power flow and significant load variation.
- SRC topologies are more suitable for data centers and ultra-fast charging stations, where operating conditions are relatively stable and extremely high efficiency is required.
The industry is also beginning to adopt hybrid topology approaches that combine the advantages of both architectures to further optimize SST efficiency across wider operating ranges.
2.3 SST Structure and Fundamental Control Architecture
2.3.1 A Generalized SST Architecture
F. Wald et al., “Applications and Services of Solid-State Transformers in Active Distribution Networks—A Critical Review,” IEEE Transactions on Smart Grid, vol. 16, no. 5, pp. 3615–3637, Sept. 2025, doi: 10.1109/TSG.2025.3574007.
At present, the academic community has not yet reached a consensus regarding the optimal circuit configuration for grid-connected SST applications. Therefore, to better illustrate SST characteristics, the figure above presents a generalized and functionally comprehensive topology consisting of a three-stage power electronic converter architecture capable of interconnecting medium-voltage (MV) and low-voltage (LV) AC/DC networks.
The control architecture of a three-stage SST can be divided into three independent fundamental controllers:
- Medium-voltage converter controller
- DC/DC converter controller
- Low-voltage converter controller
The overall control framework consists of two layers:
- Fundamental controller layer (green blocks)
- Service-oriented controller layer (blue blocks)
Signals marked with an asterisk (*) represent reference values rather than measured values. Signals highlighted in red indicate key measurement nodes requiring dedicated sensing components.
1) Medium-Voltage Converter Control
As shown in the upper-left section of the diagram, the medium-voltage-side converter is an AC/DC converter whose control strategy resembles that of a conventional active front-end converter.
Its core function is to regulate the AC-side current (i_1) through cascaded current-voltage controllers while stabilizing the medium-voltage DC bus voltage (v_{dc1}) at the reference value (v^*_{dc1}).
A feedforward control structure can also be implemented by introducing the measured grid voltage (v_1) after the current controller.
The medium-voltage converter can adopt various topologies, with the Modular Multilevel Converter (MMC) being the most widely used. MMC topologies require sophisticated modulation strategies along with additional voltage-balancing and common-mode compensation controllers to ensure stable operation.
Additional service-oriented control loops can also be cascaded onto the basic control framework to generate new dq-axis current reference values.
For example:
- Harmonic compensation can be achieved by superimposing oscillating active current components onto the active current reference (i^*_d).
- Voltage/reactive power support services require voltage magnitude reference inputs such as (v^*_1).
More advanced grid-support functions can also be implemented, enabling Grid-Forming (GFM) control capability on both sides of the converter.
By introducing DC bus voltage droop control characteristics in the DC-side converter, responsibility for maintaining DC bus voltage can be distributed across interconnected grids. The energy support required for GFM operation can be coordinated through downstream low-voltage networks.
Using information such as frequency deviation and voltage deviation, SSTs can further exploit load-side active power flexibility to achieve internal power flow regulation.
2) DC/DC Converter Control
The upper-middle DC/DC conversion stage shown in the diagram is primarily responsible for:
- Maintaining low-voltage DC bus stability
- Transferring power from the MV DC bus to the LV DC bus
Using the Dual Active Bridge (DAB) topology as an example, bidirectional power transfer is achieved by controlling the phase shift between the primary and secondary voltages of the medium-frequency transformer (MFT), thereby controlling current direction and magnitude.
The core control objective of this stage is implemented through the power flow controller module shown in the center of the diagram, whose inputs include:
- Measured low-voltage DC bus voltage
- Reference voltage (v^*_{dc2})
Lower-level control and modulation techniques can be flexibly selected according to topology and operating conditions, including:
- Linearized control
- Disturbance observer-based control
- Sliding mode control
Advanced soft-switching algorithms such as Zero Voltage Switching (ZVS) in DAB converters can significantly:
- Improve conversion efficiency
- Extend device lifespan
- Reduce thermal stress on power switches
Today, advanced soft-switching techniques are increasingly being adopted in current-source inverters and specialized complex converter topologies to further improve efficiency.
3) Low-Voltage Converter Control
The low-voltage-side DC/AC converter shown in the upper-right section of the diagram adopts different control strategies depending on application requirements.
At the fundamental control level, the converter can operate in either:
- Grid-Forming (GFM) mode
- Grid-Following (GFL) mode
According to industry-standard definitions, a Grid-Forming controller must maintain its internal voltage phasor constant—or nearly constant—within sub-transient and transient time scales.
This can be achieved through:
- Virtual synchronous machine (VSM) control
- Virtual oscillator control (VCO)
- Advanced droop-control techniques
In Grid-Following mode, the converter can adopt control strategies similar to those used on the medium-voltage side, enabling active/reactive power exchange and harmonic compensation according to low-voltage grid requirements.
Depending on the target application, the low-voltage-side grid control and service module shown in the lower-right section of the figure may receive various feedback signals and references, including:
- Active power deviation references ((\Delta P^*_2))
- Frequency deviations on both grid sides ((\Delta f^_1), (\Delta f^_2))
- Low-voltage-side voltage deviation ((v^*_2))
2.3.2Fundamental Control and Measurement
In a three-stage Solid-State Transformer (SST) topology, the measurement of operating currents and voltages is primarily driven by the control requirements of the medium-voltage-side converter, DC/DC converter, low-voltage-side converter, and overall system-level coordination. The key measurement parameters are summarized as follows:
1) Key Voltage Measurements
| Measurement Item | Function and Control Purpose |
|---|---|
| Medium-Voltage DC Bus Voltage ((v_{dc1})) | The primary control objective of the MV-side AC/DC converter is to maintain this voltage at the reference value (v^*_{dc1}). It serves as the key feedback variable for the cascaded current-voltage control loop. |
| Low-Voltage DC Bus Voltage ((v_{dc2})) | The DC/DC converter regulates power transfer by comparing the measured voltage with the reference value (v^*_{dc2}), ensuring stable operation of the LV DC bus. |
| Medium-Voltage AC-Side Voltage ((v_1)) | Used for feedforward control in the MV-side converter to improve current-loop dynamic response. It also provides feedback for voltage and reactive power (VAr) support functions, enabling reactive power regulation. |
| Low-Voltage AC-Side Voltage ((v_2)) | A core feedback signal for the LV-side converter operating in either Grid-Following (GFL) or Grid-Forming (GFM) mode. In GFL mode, it is used to track grid voltage; in GFM mode, it is used to maintain constant output voltage ((v_2 = v^*_2)). |
| Medium-Frequency Transformer (MFT) Primary/Secondary Voltages | In DC/DC converters such as Dual Active Bridge (DAB) topologies, these voltage measurements are used to regulate phase shift and control both the direction and magnitude of power flow. |
2) Key Current Measurements
| Measurement Item | Function and Control Purpose |
|---|---|
| Medium-Voltage AC-Side Current ((i_1)) | The directly controlled variable of the MV-side converter. Current regulation enables active/reactive power allocation and harmonic compensation. |
| Low-Voltage AC-Side Current ((i_2)) | A control feedback variable for the LV-side converter. In GFL mode, it tracks active/reactive current commands; in GFM mode, it reflects load current demand and supports indirect power regulation. |
| DC Bus Capacitor Current | Indirectly reflects the power balance status between MV-side and LV-side converters. It is used to monitor DC-link energy fluctuations and support dynamic control stability. (No dedicated symbol is defined, as it is implicitly included in the dynamic regulation of (v_{dc1}) and (v_{dc2})). |
| dq-Axis Current Components ((i_d), (i_q)) | Current components in the synchronous rotating reference frame obtained through coordinate transformation. (i_d) corresponds to active current, while (i_q) corresponds to reactive current. These are the key intermediate variables for decoupled power control and harmonic compensation. Oscillating current components may also be superimposed for harmonic mitigation purposes. |
