摘　　要：介绍了一种基于零电压软开关技术和双闭环控制模式的大功率等离子喷涂高频开关电源。实验表明该电源具有优良的性能和较高的效率,可以实现全范围软开关,具有良好的限流和抗偏磁能力,能够很好满足等离子喷涂的工艺需求。A novel plasma spray power supply based on ZVS soft-switching technology and double close loop control mode is presented in this paper. The 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. The tests stated that the inverter power supply has excellent characteristics and higher efficiency and can meet the demand of large power plasma spray process well.
