  3. By compared with the simulation results and the experiment results, we come to the conclusions that : ( 1 ) circuit with assistant network can widen soft - switching extent in lagging arm, reduces duty - cycle loss on the secondary, diminishes switching dissipation of inverter spot - welding power source. ( 2 ) the range of resonant capacitor, the important factor to soft - switching process, not only affects zero - voltage turn - off of power switches, but also affects the range of zero - voltage turn - on of power switches. so resonant capacitors must be considered according to many aspects ; ( 3 ) it easily fulfils soft - switching condition in lagging arm as leakage inductance of power transformer increases, but bigger leakage inductance of power transformer increases opening dissipation of transformer and decreases efficiency of soft - switching inverter power source

    通過模擬結果與軟開關點焊逆變器試驗結果的對比分析，得到了如下主要結論：採用輔助網路可以完全拓寬全橋軟開關逆變器的滯后橋臂軟開關范圍，減小了次級占空比丟失，降低了逆變電阻點焊電源的開關損耗；諧振電容是影響軟開關工作狀態的重要因素，其大小不僅影響開關管的零電壓關斷，同時也影響開關管的零電壓開通范圍，因此，諧振電容應該綜合考慮；功率變壓器漏感越大，越容易滿足滯后橋臂的軟開關條件，但是大的漏感也使變壓器的通態損耗增加，降低了軟開關逆變器的效率。
