A ZVS Interleaved Boost AC / DC Converter Using Super Capacitor Power for Hybrid Electrical Vehicles

This paper presents the supercapacitor power management method for the Hybrid Electricals Vehicles.A simple zero-voltage switching(ZVS) interleaved boost power factor correction(PFC) AC/DC converter is used to charge the traction battery of an Hybrid Electrical Vehicle. The auxiliary circuit provides limited current to charge and discharge the MOSFETs output capacitors during turn-On times at zero voltages. The circuit maintains ZVS for the universal input voltage (85 to 265 Vrms ), and having the very wide range of duty ratios (0.07 to 1). The proposed tropology consist of super capacitor, which connected across the hybrid electrical vehicle. The main objective of this paper is to study the management of the energy provided by supercapacitor by using multi full bridge converter tropology, which is having maximum voltage of 270v. The output of the full bridge converter is connected to the hybrid electrical vehicle. The supercapacitor output is connected to the load through planar Transformer, it provides peak voltages at starting of Electrical Vehicle.The experimental and simulation results are presented.
