A motor drive controller is provided that includes a current source inverter. The current source inverter includes driver circuitry configured to generate switching commands; a variable current source configured to generate a variable current that regulates power in a motor; and motor commutation circuitry configured to receive the variable current and switching commands, and to commutate phase currents that are output to the motor.

Motor drive controller for an electric motor drive system

Embodiments of the present disclosure relate to an electric motor drive system for driving a low-voltage motor. The low-voltage motor includes a rotor and a stator that comprises a number of single-turn coils. A motor drive controller can control the low-voltage motor. The motor drive controller includes a current source inverter. The current source inverter includes driver circuitry configured to generate switching commands, a variable current source and motor commutation circuitry. The variable current source can generate a variable current that regulates power in the low-voltage motor. The motor commutation circuitry receives the variable current and switching commands, and commutates phase currents that are output to the low-voltage motor.
