摘　　要：提出了一种新的软开关逆变弧焊电源的设计方案 ,该方案基本上可实现空载、短路、燃弧全负载范围内的软开关状态。提出了引入无功电流分量解决空、轻载时软开关失败问题的方案 ,以及几个主要谐振参数的设计方法。在实践中采用本方案 ,表明降低了开关应力及损耗 ,提高了整机可靠性 。This article introduces a new design plan of soft switch invert welding power source, which can almost get in soft switch state under no-load , short circuit or load. Also it gives a plan of solving the problem of soft switch in no-load and low load by taking idle current component into account, and the design methods about the main resonance parameter. It shows that can lower the switch stress, wastage, and cost but improves the reliability.
