在消费类和商用产品中，反激式变换器必须遵守相关传导和辐射电磁干扰EMI（electromagnetic interference）的严格标准。随着高速宽禁带WBG（high-speed wide bandgap）半导体器件在现代电力电子中的普遍应用，系统布局越来越紧凑，EMI的管理变得日益复杂。本文综述了针对传导EMI的成熟建模技术与抑制策略，重点分析了差模DM（differential mode）和共模CM（common mode）噪声，以及反激式变换器中的辐射EMI。讨论内容涵盖了器件级设计和变换器系统优化2个层面的解决方案。

Abstract

收起

Flyback converters in consumer and commercial products must adhere to strict regulatory standards for conducted and radiated electromagnetic interference (EMI). Managing EMI has become increasingly complex in modern power electronics, particularly with the integration of high-speed wide bandgap (WBG) devices into compact system layouts. A review of established modeling techniques and mitigation strategies for conducted EMI is presented, focusing on differential mode (DM) and common mode (CM) noise, alongside radiated EMI in flyback converters. The discussion encompasses solutions at both component-level design and converter system optimization.

Key words

Flyback / EMI / conducted EMI / radiated EMI / differential mode (DM) / common mode (CM)
