Soft switching can improve the converters efficiency and reduce EMI. In comparison of some methods of approaching soft switching, this thesis presents a Diode Auxiliary Resonant Commutating Network which is composed by an auxiliary bridge and a resonant commutating inductor. This topology not only well realizes zero voltage switching, but also overcomes the parasitic oscillation in the secondary side Diodes. Simultaneously, this topology makes both the secondary side diodes and auxiliary diodes operate on the soft switching state too, which reduces more switching losses and provides requirement for the system to run stably under the condition of self-cooled.
软开关能够提高变换器的效率和降低EMI,通过比较目前多种实现软开关技术方案,本文研究了一种由辅助桥臂和谐振电感组成的二极管辅助谐振换流网络,不但很好地实现了ZVS,并且克服了副边二极管上寄生振荡;同时,该拓扑也使副边二极管和辅助二极管都工作于软开关状态,进一步降低了开关损耗,为系统能够在自冷的条件下稳定运行创造了条件。
