—This The Pulse Width Modulation (PWM) DC-to-AC inverter has been widely used in many applications due to its circuit simplicity and rugged control scheme. It is however driven by a hard-switching pulse width modulation (PWM) inverter, which has low switching frequency, high switching loss, high electro-magnetic interference (EMI), high acoustic noise and low efficiency, etc. To solve these problems of the hard-switching inverter, many soft-switching inverters have been designed in the past. Unfortunately, high device voltage stress, large dc link voltage ripples, complex control scheme and so on are noticed in the existing soft-switching inverters. This proposed work overcomes the above problems with simple circuit topology and all switches work in zero-voltage switching condition. Comparative analysis between conventional open loop, PI and fuzzy logic based soft switching inverter is also presented and discussed.

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.
