resonant circuit

Working principles of Buck chopper for regulating circuit and LCC series-parallel resonant circuit in the CCM work mode were analyzed using the fundamental wave analysis method, and the converter steady state model were deduced as well as the detailed design process and calculation method.

针对Buck调压电路和LCC串并联谐振电路在CCM工作模式下，分析其工作原理，采用基波分析法推导变换器稳态模型，给出详细的设计计算方法。

Such as series or parallel resonant circuit.

如串联或并联谐振回路.

At power frequency, since the capacitive reactance of SVC's filter circuit is much larger than system inductance, the parallel resonant could not happen.

在工频频率下，SVC滤波支路的容抗远大于系统感抗，不会产生并联谐振。

The proposed auxiliary commutation circuit consists of one resonant inductor and two bidirectional switch, which provides the ZVS condition to the main switch without increasing voltage or current stresses.

提出的辅助变换电路由一个谐振电感和两个双向开关组成，此电路没有增加主开关的电压和电流应力，却给主开关提供了ZVS的条件。
