具有集成串联电容的多层柔性印刷电路平面变压器用于LLC变换器

The LLC resonant converter is popular but needs a discrete series resonant inductor and a capacitor. In order to cut down component count, a novel multilayer flexible printed circuitry (FPC) planar transformer with integrated series capacitance and inductance is proposed in this paper. This planar transformer consists of two sets of multilayer open-ended windings coupled with each other to produce...
