Sliding-Mode Control of the DC-DC Ćuk Converter in Discontinuous Conduction Mode

In this paper, a novel approach for two-loop control of the DC-DC Ćuk converter in discontinuous conduction mode is presented using a sliding mode controller. The proposed controller can regulate the output of the converter in a wide range of input voltage and load resistance. Controller parameters are selected using PSO algorithms. In order to verify the accuracy and efficiency of the developed sliding mode controller, the proposed method is simulated in MATLAB/Simulink. It is shown that the developed controller has, the faster dynamic response compared with standard integrated circuit (MIC38C42-5) based regulators.
