基于柔性多層繞組的集成EMI濾波器

摘要：本文提出一種基于柔性多層集成L-C繞組的新型EMI濾波器集成結構。 通過采用此種結構，可以將共模電感，差模電感與共模電容集成為1個單元。與平面PCB繞組的集成EMI濾波器比較， 具有銅損顯著減小的特點。本文還介紹了實驗樣機和實驗結果。 敘詞：柔性多層繞組 EMI濾波器 無源集成 平面PCB Abstract：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 common- mode 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.
