Abstract
The power switches of an inverter are mechanically integrated with an electric motor of a vehicle and are mounted on the end plate of the motor and employ short connections between the motor a-c terminals and the inverter a-c output terminals. Bond wireless modules are employed. The electronic controls for the inverter are mounted on a main control board which is positioned remotely from the inverter and is not subject to the heat and EMI produced by the inverter.
