Abstract: The practical use of current source DC-DC resonant converters has an outstanding performance in terms of its robust and fast performance. In this paper, the non-linear behavior during the battery charging application is solved using an adaptive Sliding Mode Control (SMC) technique. The SMC has a robust feature in fast transient responses over large load disturbances. The proposed converter uses Contactless Energy Transfer (CET) system that provides a suitable reactive power compensation for the design. The winding parameters of the inductance are mathematically modeled with low coupling factor to remove the voltage and current harmonics. The designed converter is subjected to input side perturbation for a non-linear disturbance and the output obtained using the Sliding Mode Controller is analysed. The non-linearity at the output voltage is reduced when using the SMC. The controller design show the setting time of the DC voltage under such disturbance is reduced to 97%. The proposed system is mathematically modeled and simulated using MATLAB/Simulink. The prototype model is designed and the results are analyzed.
