A technology review paper for drives used in electrical vehicle (EV) hybrid electrical vehicles (HEV)

摘要

The pollution of environment is increasing due a very large numbers of conventional vehicles present today. To reduce pollution the electric and hybrid electric vehicle are very beneficial. As the decade of low cost fuel is coming to an end the electric vehicle or hybrid electric vehicle is a good alternative to the conventional vehicles. These electric vehicles are driven by an electric motor may be AC or DC fed by battery through electric converter. The various drives used for the EVs & HEVs are discussed in this paper. The main two types of drive based on the supply are used DC or AC drive. The AC drives consisting of three phase permanent magnet synchronous motor (PMSM) is most popular amongst them. The other widely used drives are three phase Induction motor (IM), Switched reluctance motor (SRM), Brushless DC motor (BLDC). These motor are fed by different power electronic converters such as DC-DC converter, DC- AC converters per the supply requirements.
