摘要

本文介绍了采用前馈补偿方法改善数控同步整流buck型dc-dc变换器的暂态响应。通过状态空间方程引入前馈单元的传递函数。采用前馈元件的变换器稳态特性与不采用前馈元件的变换器相同，但输出电流变化和输入电压变化的瞬态响应明显改善。

Transient response improvement of digitally controlled DC-DC converter with feedforward compensation

This paper describes transient response improvement of digitally controlled synchronous rectification buck-type dc-dc converter using feedforward compensation. Transfer function of the feedforward element was introduced by the state space equation. The steady state characteristics of the converter using the feedforward element were same as the converter without using the element, but transient responses for output current change and input voltage change were significantly improved.
