A New Multi-Input Dc-Dc Converter for Hybrid Electric Vehicles

Abstract

This project proposes a new multi-input isolated DC-DC converter for hybrid electric vehicles application. In this work, fuel cell and energy storage system are utilized as the input sources for the proposed system. Fuel is considered as the main power supply. Utilized to charge the battery, increase the efficiency, reduce fuel economy and supplying the output load ,charging and discharging the battery can be made by the FC and PV sources  simultaneously or individually. The main advantage of proposed converter is that, the proposed multi input converter has a capability of providing the demanded power by load in absence of one or two resources.
