摘要

本文介绍了采用前馈补偿器改进数字PID和I-PD控制同步整流buck型dc-dc变换器的暂态响应。考虑输入电压、输出电压、负载电流和高侧开关导通时间的关系式，给出了前馈补偿器的数值计算公式。带前馈补偿器的变换器与不带前馈补偿器的变换器稳态特性相同。然而，输入和负载瞬态响应显著改善。

Transient response improvement of digitally controlled buck-type dc-dc converter with feedforward compensator

This paper describes transient response improvement of digital PID and I-PD controlled synchronous rectification buck-type dc-dc converter using feedforward compensator. Numerical formulae of the feedforward compensator were introduced by taking into account the relational expression including input voltage, output voltage, load current and ON-time of high-side switch. The steady-state characteristics of the converter with feedforward compensator were the same as the converter without one. However, input and load transient response were significantly improved.
