Simulation of Soft Switch Circuit for Spot Welding Inverter Power

Based on the analysis of main circuit for spot welding inverter power, a topology of the spot welding inverter with phase-moved resonance zero-current and zero-voltage switch is presented in this paper, and the principle of circuit is analyzed in detail. The simulation is carried out by use of Matlab .The simulation results show the good performance of the topology and the feasibility of being used to design resistance welding inverter power.
