The key issues of sustainable mobility are: energy, environment and safety. Therefore developing clean, efficient and intelligent vehicles, including battery electric vehicles, hybrid electric vehicles and fuel cell electric vehicles is necessary. The two major environmental risks affecting sustainability in the production of electricity using fossil fuels are green house effect and acid rain. The basic requirement of power electronic for electric, hybrid and fuel cell vehicles are: high energy density, high power density, high efficiency over wide speed and torque range, frequent start stop, continuous dynamic, capable working under severe ambient temperature and vibration environment, compatible EMI-EMC, high reliability, high endurance, and reasonable cost.
