Abstract

Zvzcs-pwm inverter combines the advantages of ZVS-PWM inverter and ZCS-PWM inverter, it can solve the problems of switching loses and extra circulation. Furthermore, it is provided with less duty cycle loss, small parasitic oscillation of the secondary side and large load rage conducted by soft-switching. A conjoint system based on MCU and DSP can make full use of the advanced ability of the event management, data processing and computing speed, which improves accuracy and real-time digital control of arc welding power. This paper introduces design of main circuit and control circuit of arc welding power and the working process of the zvzcs-pwm inverter. The simulation with matlab demonstrates the feasibility of the design.
