Hardware Implementation of Two Stage Interleaved Boost Converter for Electric Vehicle Application
Main Article Content
Abstract
This paper deals with the design and simulation of two stage interleaved boost converter (IBC) for electric vehicle (EV) applications. The IBC is considered as a better solution among the different DC-DC topologies for EV for reducing the current ripple, power loss and the size of the components. Traditional DC-DC boost converter (BC) is not applicable for high power applications. Use of interleaving technique minimizes the voltage stress on the switching devices and to be improving the converter performance. Simulation is carried out using MATLAB/Simulink software. The prototype of two stage IBC is fabricated to test the performance. Hardware results shows that the inductor power loss is minimum at a switching frequency of 5 kHz compared to that of 10 kHz. The output power at the load end is maximum for 5 kHz switching when compared with 10 kHz switching. The study shows that the operation of IBC at 5 kHz improves the performance.
