| Abstract: | To make full use of soft - switching technique in the field of welding inverter, a full - bridge zero - voltage - switching phase -shift FB -ZVS -PS -PWM} arc welding inverter which is based on UC3879 chip peakcurrent control mode and has a frequency of 200 kHz is designed. A 5 kW arc welding inverter has been designed for experiment. The experimental results show that it meets welding demands and indicates the validity of the design, and provides a foundation for practical application. |
