緩沖式軟開關直流變換器的諧波分析

摘要：　　本文對緩沖式軟開關直流變換器進行了分析，并且將變換器的輸入和輸出波形的諧波與硬開關電路相比較。結果表明該電路在具備了軟開關特性的同時，還可以有效地降低高次諧波含量。 敘詞：緩沖，軟開關，諧波 Abstract：　　The paper analyses the subber soft switching DC/DC converter and compare the harmonic with the hard switching one . The result of simulation shows that the circuit has the soft switching characters and its high harmonic has been decreasing. Keyword：snubber,soft switch, harmonic
