A modified interleaved negative output elementary Luo converter to act as front-end power factor regulating converter for electric vehicle (EV) charger is proposed in this paper. The proposed converter is simple in design and offers non-inverted DC output voltage. It has the advantages of high efficiency, almost unity power factor, low AC source current ripple resulting in power quality enhancement, better DC load voltage regulation. Due to interleaved configuration, rating of circuit components gets greatly reduced. Also, minimum numbers of circuit components pave the way for simple system design of EV charger. The converter is designed to provide stable operation when subjected to sudden disturbance in load power/supply voltage. The simulation analysis is done using MATLAB/Simulink. A prototype of converter is built and tested. Better performance of the system obtained under power factor and low current ripple. Better performance of the system obtained under power factor and low current ripple.

Keywords- Power Quality (PQ), PF Pre- Regulator, Interleaved Luo Converter, DCM mode
