A Wide Band-width Design of a Self-oscillating Resonant Converter via a Novel Discrete Time Model Criterion

Abstract

This paper presents the first steps taken towards the design of the digitally controlled self-oscillating resonant voltage regulator modules (VRMs). The design steps are given in detail with the development of the equivalent SIMULINK model of the overall system. The design aims to enlarge the bandwidth of the converter via selecting the crossover frequency of the closed loop system. SIMULINK and preliminary analog-mixed prototype results are given to verify the proposed work
