| Abstract: | In the full-bridge phase-shifting ZVS welding inverter,the PWM control and the soft-switching are combined together,so it possesses the virtues of two kinds of control and contributes to the welding inverter's development of minimizing,light weight and low cost.In design of full-bridge phase-shifting ZVS welding inverter,the application of special phase-shifting chip simplifies the control circuit,strengthenes control functions for the welding inverter and improves performance of the welding inverter evidently. |
