摘要 针对电力电子变换器高频化发展趋势下电磁干扰(EMI)问题及其给高功率密度化设计带来的挑战,该文利用柔性多层带材(FMLF)技术,提出一种结构对称型EMI滤波器电磁集成设计方案。此方案通过共模(CM)电容-线电感和差模(DM)电容-CM电感基本集成单元推演出基于UU型磁心的L/N对称型EMI滤波器全集成结构,并采用合理的端口配置方式实现CM和DM滤波元件功能解耦,从而简化CM和DM集总等效电路,进而简化其参数分析、整定和设计。以一台输出功率为500W的SiC-MOSFET高频电压源逆变器为实验平台,在利用Maxwell软件进行合理性验证的前提下,分别设计分立型、磁集成型和电磁集成型EMI滤波器样机并进行对比实验,验证了所提方案的可行性和有效性。实验结果表明,在CM和DM插入损耗设计目标相同的情况下,所提电磁集成方案可有效减小体积和质量,有助于提升系统功率密度。

Abstract:Aiming at the electromagnetic interference (EMI) issue and the associated challenge to high power density design under the trend of high frequency of power electronic converters, a flexible multi-layer foil (FMLF) technique based electromagnetic integration scheme of a structure-symmetrical EMI filter is proposed in this paper. In this scheme, the UU-cores based fully integrated structure of L/N-line-symmetric EMI filter is derived from the basic integrated units of common-mode (CM) capacitor & line-inductor, and differential-mode (DM) capacitor & CM inductor. Moreover, a reasonable terminal-configuration is utilized to realize the function-decoupling of CM and DM filtering components, which can predigest the CM and DM lumped equivalent circuits, there by simplifying the parameters' analysis, calibration and design. Taking a high-frequency SiC-MOSFET voltage source inverter with 500W output power as the experimental platform, the discrete, magnetic integrated and electromagnetic integrated EMI filter prototypes are built for comparative experiments on the premise of using Maxwell software to verify the rationality and feasibility of the proposed scheme. In addition, the results indicate that the proposed electromagnetic integrated approach can effectively reduce the size and weight, and contribute to increasing the system power density under the same design objectives of CM and DM insertion losses.
