Harmonic Capture and Loss Control of Current Sensors under the Trend of High Frequency Photovoltaics
Introduction With the large-scale application of wide bandgap semiconductor devices such as SiC (silicon carbide) and GaN (gallium nitride) in photovoltaic inverters, the system switching frequency has been increased from the traditional 20kHz to over 100kHz, and even exceeded 200kHz. Although high-frequency conversion can reduce the size of inverters and improve power density, it also […]
