Output feedback controller for series resonant converter using linear matrix inequality

Series resonant converters with high frequency operation property play important role in small and light weight power supply design. In this paper robust controller synthesis by linear matrix inequality approach is presented for series resonant converters. The achieved controller has been designed based on a multi input - multi output model of the converter. Moreover, it reveals output voltage regulation feature that is robust against load variations and reference voltage changes. Results obtained from a series of simulations validate the suggested scheme and its performance.
