In this paper, major recent electric vehicle programs in North America, Europe and Japan are reviewed. The development of electric vehicles for fleet operation has been emphasized in the past few years. The development of electric passenger cars for urban transit is catching up lately. All major auto makers have had their own concept electric vehicle programs, targeting at commercial productions in the 1990's. With different objectives for various electric vehicles, the considerations such as cost, reliability, efficiency, maintenance, durability, weight, size and noise level should be compromised for propulsion system design. Consequently, dc motor drives, induction motor drives and permanent magnet brushless dc motor drives will continually be used for EV propulsion systems in the future, with dc drives being gradually replaced by ac drives. The rapid advances in power semiconductor devices and microprocessors have made it possible to build reliable and cost-effective ac drive systems. IGBTs, darlington transistors and power MOSFETs will still be the major power semiconductor devices for EV motor controllers. Attention should also be paid to the new devices such as integrated IGBT modules and MCTs.
