PWM Sliding Mode Voltage Controller For Buck Converter In Discontinuous Mode

Control of Buck converter is a complex task due to the nonlinearity in the converter that are introduced by the external changes. This paper presents a systematic, simple and easy to follow design procedure for sliding mode voltage controlled buck converters operating in discontinuous conduction mode. The dynamic equations much essential in describing the buck converter are represented in a lucid manner. The modelled and simulated version of the sliding mode controller is presented here in this paper. Pulse width modulated (PWM) signal generated by sliding mode voltage controller (SMVC) using appropriate feedback has been successfully utilized to obtain improved performance of the converter. The paper focuses on modelling of a control circuit in Matlab/Simulink.
