Design and Optimization of Power Management for Hybrid Vehicle Based DC_DC Converter Multi Input Topology

Among many types of FCs, proton exchange membrane FC (PEMFC) is one of the most promising power sources due to its advantages, such as, low operation temperature, high power density and low emission. However, using only PEMFC for electric vehicle may not be feasible to satisfy the peak demand changes especially during accelerations and braking. So, hybridizing PEMFC and an energy storage system (ESS)decreases the FC cost and improves its performance and life. Battery (B) appears to be the most powerful candidate to hybridize with PEMFC for vehicular applications . The ultra capacitor (UC) allows to fulfill the slowest dynamics of the FC during peak power demand and to recover the breaking energy. The different electrical parts of the electrical vehicle exchange energy with the DC link through DC/DC and DC/AC converters. The power Hybrid Vehicle contains two motor-wheels.
