Power Electronic Circuits and Control Strategies for Improving the Performance of EVs & HEVs

Abstract

To give cleaner air to future generation with less pollution and to protect our atmosphere from depletion of ozone layer there is a great need of adaptation of emission free vehicles like EVs and HEVs. Even though Government is giving many incentives and subsidies in making the shift towards EVs and HEVs, but due to lack of storage system, less improvement in power electronics and drive system, there is no prominent increase in the emission free transportation on road. With good storage system the cost of the EVs and HEVs are increasing when compared to ICE vehicles. A huge research is taking place in this area. This paper gives the details of Converters, Inverters and Control strategies used in EVs and HEVs to compare which is best suitable to increase the performance of EVs and HEVs.  Basic Conventional Vehicle and Hybrid Vehicle system simulation results are taken, and they are compared to understand the advantages and improving the usage of EVs and HEVs with proper storage system.
