摘要

本文提出了一种用于DC-DC变换器开关的双环数字控制方法。通过增加非线性控制环，可以消除线性数字控制环固有时滞对负载暂态响应的影响。减小过调量、欠调量和稳定时间可以改善负载的瞬态响应。基于同步降压变换器的仿真结果验证了所提出的双环数字控制方法

A Dual-loop Digital Controller for Switching DC-DC converters

This paper presents a dual-loop digital control approach for switching DC-DC converters. With an additional nonlinear control loop, the effect of inherent time delay of linear digital control loop on load transient response can be eliminated. Load transient response can be improved with reduced overshoot, undershoot and settling time. Simulation results based on a synchronous buck converter are shown to validate the proposed dual-loop digital control approach
