Abstract
An illustrative drive unit for an electric vehicle includes a first electrical motor, a first axle mechanically couplable to the first electrical motor, a second electrical motor, a second axle mechanically couplable to the second electrical motor, and a dual power inverter module electrically couplable to a source of high voltage DC electrical power. The dual power inverter module includes: a first inverter configured to convert the high voltage DC electrical power to three phase, high voltage AC electrical power and electrically couplable to provide the three phase, high voltage AC electrical power to the first electrical motor; a second inverter configured to convert the high voltage DC electrical power to three phase, high voltage AC electrical power and electrically couplable to provide the three phase, high voltage AC electrical power to the second electrical motor; and a common controller configured to control the first inverter and the second inverter.
