谐振拓扑求教,为什么PRC和LCC变压器二次侧需要加滤波电感,而SRC和LLC不用?谢谢!

如题

在杨波的论文Appendix A关于三个谐振元件结构的表述中提到:

Second, for the resonant tank, input and output source type will be determinedby tank configuration. For example, the output is must a current source for PRC since the primary side is capacitor, although PRC with voltage source could also work. This also means that there is no capacitor in parallel with input terminalssince input is assumed to be voltage source type.

在别的文章中也有类似的表述,请问要怎么理解这句话其中的原理?

请大家不吝赐教,最好能够详细说明,谢谢!

因为电源变换器一般总是等效为电压源后面接电流源,或者电流源后面接电压源。不太可能为电流源接电流源,也不太可能为电压源接电压源。
