Multi Input DC-DC Converter for Automotive Applications

Some of the serious problems which we are encountering these days are the Air Pollution, Global Warming and the rapid depletion of the Earth-s Petroleum Resources. Hence to accommodate the future challenges, it has been typically proposed to replace conventional vehicles system to new generation Electric Vehicles (EVs), Hybrid Electric Vehicles (HEVs) and Fuel Cell Electric Vehicles (FCEVs). The rapid development of technologies of Power Electronics and Electric Vehicles, suitable energy storage systems allows the production of high efficiency electric vehicles. Hybrid Electric Vehicle (HEV) is one such technology which has this potential and gained enormous attention because of depleting conventional resources and has measured carbon emission there by providing better fuel efficiency with reduced harmful emission and also enhances the performance. Instead of providing single input converter to each load, the use of Multi Input Converter (MIC) in the hybrid system reduces the number of components used, thereby reducing the size of power circuit with higher efficiency which ensures more reliable system and provide regulated power to the vehicles. Due to the intermittent nature of renewable sources, there might be drastic changes in the climatic conditions and are not always same in the given period of time. Due to this intermittent nature the output power changes with change in the climatic condition. -Rechargeable Energy Storage System- (RESS) is used as a backup energy source in case when load demand is high and production is low from the four input renewable energy sources.
