反激式电源中电磁干扰及其抑制

Introduction and Restraint of EMI in Flyback Power Supply

在介绍Flyback反激式DC/DC电源及其性能的基础上,主要讨论了该电源中的网侧谐波及其抑制,开关缓冲电路,光耦隔离等问题。

Based on the brief introduction of Flyback power supply and its function, three questions of EMI are discussed: generation and restraint of harmonic at the network side in the power supply, switch buffer circuit and optical coupler isolation.
