摘要：
Driven by the development of high-frequency power electronic converters, the electromagnetic interference (EMI) issue has become more prominent. Therefore, an EMI filter plays an essential role in a power electronic system; the optimization design of EMI filter has a far-reaching impact on the coming industrial application field. Based on the Silicon carbide (SiC) MOSFET single-phase inverter, this paper investigated a full integration strategy of EMI filters with the UU-type core and flexible multi-layer foils (FMLFs). The FMLFs contain electrical-, dielectric- and insulation layers. Through the ingenious design of the FMLFs and appropriate connection arrangement of the terminals, all the filtering elements of an EMI filter can be integrated into the same core-unit. Beginning with the integration design of CM filtering elements, this work designsed three fully integrated EMI filter structures according to different DM attenuation requirements: CM inductor & capacitor type, CM inductor & capacitor-DM capacitor type and CM inductor & capacitor-DM inductor & capacitor type, respectively. In the Maxwell- ANSYS simulated environment, the feasibility of the design was analyzed through finite element simulation (FES). Finally, the practical measurements have verified the feasibility and validity of the proposed schemes. © 2022 Chin. Soc. for Elec. Eng.
