摘要
提出了一种采用激磁电感，配合漏感和分布电感，实现大功率 零电压软开关的新型电路拓扑，分析了实现大功率软开关的关键问题。成功地将电流注入移 相控制技术和大功率软开关技术相融合，研制的新型大功率软开关弧焊逆变器实现了全范围软开关。
A novel circuit topology with soft switching by utilizing magnetizing inductance, leakage inductance and distributed inductance is presented. The critical factors affecting the realization of high power soft switching are discussed. The current injection phase shifting technique is introduced into the research of high-power soft-switching converter successfully. A novel high-power welding converter with full range soft switching is produced.
