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 discontinuousconduction mode is presented using a sliding mode controller. The proposed controller can regulatethe output of the converter in a wide range of input voltage and load resistance. Controllerparameters are selected using PSO algorithms. In order to verify the accuracy and efficiency of thedeveloped sliding mode controller, the proposed method is simulated in MATLAB/Simulink. It isshown that the developed controller has, the faster dynamic response compared with standardintegrated circuit (MIC38C42-5) based regulators.
