Why Main Contact Welding Occurs in HVDC Contactors:Technical Causes, Prevention Methods, and Engineering Solutions

In PV, energy storage, and EV charging systems, high-voltage DC (HVDC) contactors are critical electrical components that ensure safe and reliable system operation. They are widely used in battery energy storage systems (BESS), EV charging stations, PV inverters, and DC distribution systems. As system voltage and power levels continue to increase, HVDC contactors must withstand […]
