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
