摘要

设计了一种紧凑封装的共模有源滤波器，用于抑制开关电源的共模传导辐射。在电压检测电压补偿前馈拓扑结构中实现了非常紧凑的结构。对所提出的滤波器进行了分析，并将样机应用于实际的开关电源(SMPS)板，通过实验验证了该滤波器的有效性。

A common-mode active filter in a compact package for a switching mode power supply

A common-mode (CM) active filter was designed in a compact package to suppress CM conducted emission at a switching mode power supply. A very compact structure was implemented in the voltage-sense voltage-compensation feedforward topology. The proposed filter was analyzed, and a prototype was applied to a real switching mode power supply (SMPS) board, demonstrating its usefulness by experiments.
