An Interleaved ZCS Supplied Switched Power Converter for Fuel Cell-Based Electric Vehicle Propulsion System

This research paper explains the modeling and simulated responses of the proposed interleaved zero current switching (ZCS) employed full bridged switched converter considering fuel cell vehicle application using MATLAB/Simulink simulation software. The aim of the proposed model is to reduce ripple in input current as well as reduction in dimension of used passive devices. It also minimizes the voltage/current ratings of the operated components with diminished switching/conduction losses. Moreover, an interleaved bidirected snubberless DC–DC as a voltage doubler circuit system is employed as energy repository for fuel cell-based electric propulsion system. The bidirected DC-DC converter allows higher switched frequency action.
