摘要：
Through the analysis of the circuit structure and electromagnetic interference (EMI) conduction path, the structure of the traditional harmonic filter is optimized so that it has the ability to suppress EMI. Using the structure of planar magnetic integration not only ensures the basic harmonic suppression ability of the harmonic filter, but also improves the EMI suppression effect. With a single-phase voltage source 500-W SiC inverter as the platform, the feasibility and effectiveness of the design scheme are experimentally verified. The results indicated that the planar magnetic integrated harmonic EMI filter satisfies the design requirements. Additionally, the proposed planar magnetic integration scheme can significantly reduce the volume and weight of the filter and increase the power density of the entire system.
