摘　　要：本文提出一种基于柔性多层集成L-C绕组的新型EMI滤波器集成结构。通过采用此种结构,可以将共模电感,差模电感与共模电容集成为1个单元。与平面PCB绕组的集成EMI滤波器比较,具有铜损显著减小的特点。本文还介绍了实验样机和实验结果。This article introduces a new EMI filter integration structure based on flexible multi-layer L-C wiring. The application of this structure will integrate common-mode choke, differential-mode choke and commonmode capacitance into one unit. Compared with integrated EMI filter based on plane PCB wiring, it greatly lowers the copper loss. This article also presents an experimental sample and experimental results.
