Abstract

A new approach for the analysis and design of sliding mode controller for PWM based Buck-Boost DC-DC converter in continuous conduction mode of operation is presented. The main advantage of this non-linear controller is that there is no restriction on the size of the signal variations around the operating point. Small as well as large signal variations around the operating point are considered. Sliding mode controller for PWM based Buck-Boost converter using state space averaging model has been designed and discussed. The present controller has been simulated on a digital computer and its dynamic performance has been shown to be satisfactory.
