“…These methods have to introduce another complicate circuit with several active fasting switches for power decoupling function [4,5,6,7,8,9,10,11,12,13,14,15,16]. Although these methods can significantly reduce the bulk cap [17,18,19,20,21,22,23,24,25,26,27], the decoupling circuits are too complex to use, especially for commercial type-c PD applications.…”
