Abstract
In last few decades, a number of power factor correction (PFC) converter topologies are developed to improve the input power factor and to improve the input power quality of the converters. In this paper, four such converter topologies are selected and compared for electric vehicle battery charging application. A comparative analysis is done for boost PFC (B-PFC) converter, interleaved boost PFC (IB-PFC), bridgeless interleaved boost PFC (BIB-PFC) and pulse width modulated (PWM) PFC converter in terms of performance and efficiency in MATLAB/Simulink environment. Their efficiency evaluation is done considering the device losses by selecting some practical devices of the desired ratings. The heat dissipation problem due to diode-bridge rectifier in the B-PFC converter is overcome in PWM-PFC and BIB-PFC. The simulation results of the four converters shows high power factor and high efficiency. The analysis shows that PWM PFC converter is more suitable for electric vehicle applications.
