Abstract
A control system (48) having a motor (28) is disclosed. The control system (48) may include a converter (32) operatively connected to a power source (36), an inverter (34) operatively connected to the motor (28), and a controller (50) operatively connected to the converter (32) or inverter (34). The controller (50) may be configured to receive control command signals, receive state feedback signals, and generate duty cycle signals for upper and lower arms of each phase (40) of the motor (28) based at least in part on the control command signals and state feedback signals. The duty cycle signals may minimize neutral point current in the converter (32) or inverter (34).
