Abstract

In this paper, based on quantitative feedback theory, the authors design a robust controller for a series resonant DC-to-DC power converter. In order to analyze the stability, a small-signal model of series resonant power converters is adopted. Simulation results illustrate that the required performances, sensitivity, maximum overshoot and allowable settling time can be achieved subject to different loads. In addition, the performance is evaluated with the PSpice circuit simulator.

基于qft的串联谐振DC/DC变换器鲁棒控制器设计
本文基于定量反馈理论,设计了一种串联谐振dc - dc功率变换器的鲁棒控制器。为了分析其稳定性,采用串联谐振功率变换器的小信号模型。仿真结果表明,在不同载荷作用下,该系统均能达到要求的性能、灵敏度、最大超调量和允许沉降时间。此外,利用PSpice电路模拟器对其性能进行了评估。
