摘要
本文提出了一种带辅助开关的半桥式串联共振型DC—DC变换器 ,并对主电路的构成原理 ,电路拓扑和存在的工作模式以及在轻负荷时利用辅助开关的动作防止开关频率的降低进行了详细的分析讨论。作出状态轨迹图。通过实测 ,获得良好的特性。
A detailed analysis is made about the half bridge type series resonant DC DC converter with auxiliary switches on such matters as the composition principle of the main circuit,the circuit topology,existing state sequence and how to use the auxiliary switch to prevent the decrease of the switch frequency.A corresponding state locus diagram is made.Through measuring,good characteristics are obtained.
