Abstract :
A novel integrated EMI filter structure is proposed in this paper, based on FML foils. It integrates common mode inductors and differential mode capacitors and inductors into a single unit. A novel interleaved flexible multi-layer (FML) foil structure is proposed to overcome the difficulty of enlarging the DM capacitance. A prototype is constructed based on this concept and was put into a front-end converter to replace a discrete EMI filter. Testing result presented.
