摘　　要：文章采用新型软开关电路拓扑 ,结合应用移相控制软开关技术和电流峰值控制技术 ,研制出一种新型软开关弧焊逆变器。仿真和实验结果表明 ,所研制的弧焊逆变器能够实现全范围的软开关 ,并且具有良好的限流和自校正能力 ,可以有效的解决功率变压器的偏磁问题。A novel soft switching topology is presented and the phase shifted soft switching technology and peak current injection technology are applied in the research of soft switching arc welding inverter. The simulation and experiments results indicated that the novel inverter is with full range soft switching and is capable of auto correction and current limiting which solves the magnetic bias of power transform effectively.
