Abstract

Fuel cell powered BLDC motor drive for electric vehicle is the cleaner energy conversion solution with higher efficiency. DC-DC power conversion in this drive plays a significant role in adoptability, efficiency and reliability of the overall drive. This paper presents an enhanced Luo converter for increased voltage gain with additional multiplier stage and reduced capacitor voltage stress owing to reduced clamping voltage. The topology, operational modes, and mathematical analysis of the proposed power conversion are presented. Simulation is carried out in MATLAB/SIMULINK platform which analyzed operational parameters such as output voltage ripple, output voltage regulation, converter components voltage stress, and inductor current ripple. Also, the proposed converter structural advantages are compared to existing converters. The findings on operational and structural parameters resulted in stringent output regulation less than 1 percent for desired output voltage. Also, 41.67 percent reduction is observed for voltage stress across converter capacitors. Thus, an enhanced Luo DC-DC power conversion is designed and validated for fuel cell powered BLDC motor-based EV drive.

Keywords: Fuel cell, FCEV, Boost converter, Luo converter, voltage stress, PI controller .
