有源箝位零電壓開關DC-DC變換器拓撲的研究

摘要：　　有源箝位ZVS DC-DC變換器實現了主開關管和輔助開關管的軟開關，減少了開關管上的電壓應力和反向恢復相關的損耗。本文在有源箝位ZVS單元模塊基礎上，對有源箝位ZVS DC-DC 變換器進行了全面的分析和研究。 敘詞：有源箝位 零電壓開關 DC-DC變換器 Abstract：　　The DC-DC converters can operate on soft switching in ZVS active clamping,so it can reduce voltage stress on switches and loss related to reverse　recovery.Based on ZVS active clamp cells,the paper give a thorough analysis and research on ZVS active clamp DC-DC converters.
