Abstract: Study of various soft-switching welding power is a main
developing direction in the world recent years. A novel
zero-voltage-switching (ZVS) full-bridge (FB) pulse-width modulated (PWM)
inverter resistance welding power source is introduced. The inverter
resistance welding power source is controlled by an industrial
processing computer (IPC), and insulated gate bipolar transistors (IGBT),
driven by improved EXB841, are used as the power switches in the
inverter circuit. The research conclusion shows that the inverter
resistance welding power source can work reliably and stably, and has
sensible protection function for overcurrent in the circuit, and by
optimizing circuit parameters and programming software properly, power
switches can be operated with zero-voltage-switching (ZVS).
