Abstract
The functioning of the Diode Bridge Rectifier (DBR) fed charger does not abide by the international regulations such as the IEC 6100-3-2 standard. In this paper different types of topologies for bridgeless Ćuk converter are being analyzed and based on that a finest bridgeless Ćuk converter is proposed for electric vehicle charger. The proposed bridgeless Ćuk converter enhances the overall efficiency by avoiding one switch and two passive elements. To overcome the violation of the recommended guidelines of IEC 6100-3-2 standard for output inductor, the single loop voltage control is replaced with double loop controller having an inner current loop control and outer output voltage control. The proposed converter topology is operated in DCM mode to have natural benefit of zero current switching. Furthermore, to reduce the switching losses of the new topology, soft-switching technique has been implemented.On the other hand, electric vehicle battery charging, is done with the help of flyback DC-DC converter with constant current and constant voltage control regimes. This CC-CV method safeguard the battery from overloading. The whole proposed topology is designed and implemented using MATLAB Simulink. The enhanced charger performance is demonstrated by comparing the proposed charger with the typical diode bridge rectifier fed charger.
