Electronic power train control is key to fuel efficiency and lower emissions. The main inverter converts high voltage, high current DC to AC (the electric traction motor is a 3-phase AC load.) The main inverter controls the electric motor. The electronics in a main inverter are ideally designed to minimize switching losses and maximize thermal efficiency. The range of an electric vehicle is related to the efficiency of the main inverter. Efficiency is dependent upon the electronics in the inverter. The components should be able to withstand extremely high temperatures (125°C) and be as small and light as possible via means of better packaging or integration of external components to reduce overall part count.
