摘要

本文提出了一种单绕组自驱动同步整流(SWSDSR)的多输出半桥变换器，它是一种非常适合于宽输入电压范围的大电流低压应用的拓扑结构。获得了高效率、多输出能力等重要效益。利用所提出的变换器，可以通过仅从一个附加绕组获得的栅极电压波形驱动所有同步整流器。文中还介绍了25w实验室样机的设计思想和实验结果。

Multi-output half-bridge converter with self-driven synchronous rectification

This paper presents a multi-output half-bridge converter with single winding self-driven synchronous rectification (SWSDSR), which is a very suitable topology for high-current low-voltage applications with a wide input voltage range. Important benefits as high efficiency and multi-output capability are obtained. With the proposed converter it is possible to drive all synchronous rectifiers through the gate voltage waveforms obtained from only one additional winding. Design considerations and experimental results of a 25 W laboratory prototype are included in the paper.
