Control scheme for a multiple-output DC/DC current source parallel resonant converter

Abstract:

The aim of this paper is to regulate the output voltages of a multiple-output DC/DC class-D current source parallel resonant converter. To this end, a sliding mode control scheme is presented consisting of an outer voltage loop, an inner current loop and a robust modulator. To devise this control scheme, the averaged large signal model of the converter is derived. In addition, this model is used to determine the stability range of the controller parameters. Some simulation results are provided to validate the expected features of the presented control configuration.
