Comparison of Interleaved Boost Converter Topologies with Voltage Multiplier for Battery Charging Of PHEV

Dr.R.Seyezhai, V.Aarthi

This paper deals with three different topologies of voltage multiplier cells with Interleaved Boost Converter (IBC) for charging the battery of Plug-in Hybrid Electric Vehicle (PHEV). A DC-DC boost converter is used to step-up the voltage. Here, interleaving structure is used to reduce the input current ripple, output voltage ripple, power loss and to reduce the input current that is fed to the battery of the PHEV. Voltage multiplier cells are used to reduce the narrow turn-off periods. Three topologies are compared in this paper: i) Interleaved Boost Converter ii) Interleaved Boost Converter with Diode-Capacitor multiplier iii) Interleaved Boost Converter with switched capacitor and coupled inductor. Simulation studies of the proposed topologies are carried out in MATLAB. The various performance parameters are compared and the best topology is chosen for the battery charging of the PHEV. The results are verified.
