Modeling and Design of PWM based Sliding Mode Controller for Active Clamp Forward Converter

Abstract

This paper presents the step by step design procedure to model and design of sliding mode controller for Forward Converter with Active Clamp circuit (ACFC). Brief review on working principle and mathematical modeling of Converter is first given. The importance of sliding mode controller for forward converter and design procedure of the considered controller is described in detail. And the validity of designed controller and achievement of desired compensation is confirmed by the obtained results. Finally the results are analyzed by applying disturbances at source end and at load side.
