IGBT With Electric Car
Gasoline powered cars still comprise the majority of vehicles used in our society for commuting, recreation, shopping, and transportation of merchandise presently. But it is well acknowledged that gasoline powered vehicles cause serious environmental contamination whilst depleting dwindling fossil fuel resource. A solution to this problem is the propagation of electric and hybrid-electric vehicles.
Because of the restrictions in the extent and unreliable batteries, electric vehicles fell out of favor until the 1990’s. With increased acknowledgement of vulnerable gasoline supply from the middle-east and the impact on urban health due to pollution from gasoline powered cars, the hybrid-electric car has taken a foothold in the automobile market. Even from the early 1990’s it was apparent that the IGBT is the ideal power switch for motor drives in electric vehicles. The most successful electric car in the marketplace has been the Toyota Prius shown in Fig. 16 with its IGBT motor drive module. All hybrid-electric and electric cars that have been subsequently introduced into the market have relied up on IGBT-based motor drives. In addition, the regenerative braking capability, that has a big impact on the efficiency of Hybrid-electric cars, relies up on IGBTs.
Almost all manufacturers are using IGBTs now in electric and hybrid-electric vehicles made by them for delivery and control of power to the motors. This will carry on having a great influence on the ability of our society to migrate away from gasoline consumption in the future.
