SIMULATION AND IMPLEMENTATION OF AC-DC INTERLEAVED BOOST CONVERTER WITH VOLTAGE MULTIPLIER FOR PHEV

A Plug in hybrid electric vehicle (PHEV) is a hybrid vehicle which employs battery to power up the vehicle motor and it has higher efficiency and low cost compared to the conventional internal combustion engine based vehicle. In PHEV, the charging and discharging of battery is accomplished using a power electronic converter system. This paper focuses on the implementation of an AC-DC interleaved boost converter with voltage multiplier cells for charging of Plug-in Hybrid Electric Vehicle (PHEV). The IBC topology with switched capacitor and coupled inductor is chosen for this work. The proposed AC-DC converter is employed to reduce the ripples at the input and output along with multiplier block to reduce the narrow turn off periods. The output of IBC is fed to a bidirectional DC-DC converter for charging the battery in PHEV. Simulation of the proposed converter is studied in MATLAB. The performance parameters of the converter are computed. Simulation results are verified practically.
