摘要

本文提出了一种预变换器网络的设计和开发方法，通过该网络可以大大扩展降压或降压升压衍生dc - dc变换器的输入电压范围能力。所提出的集成磁形式的网络只使用三个无源电路元件和两个二极管，不需要任何有源开关元件。预变换器还可以自然地将用户功率变换器产生的正常脉动电流转换为非脉动形式，其交流纹波电流大小可以通过磁设计降至接近零的值。

Integrated-magnetic gain-enhancement input filter for switchmode power converter circuits

The design and development of a preconverter network is presented, whereby the input voltage range capability of buck or buck-boost-derived DC-to-DC converters can be extended significantly. The proposed integrated-magnetic form of the network uses only three passive circuit components and two diodes and does not require any active switch elements. The preconverter also naturally translates the normally pulsating current drawn by a user power converter into a nonpulsating form, whose AC ripple current magnitude can be reduced to near-zero value by magnetics design.<>
