1. A system comprising:
a main power source configured to provide power to at least one pulsed load;
a propulsion converter configured to drive a propulsion motor; and
a controllable-field induction electrical machine coupled to the at least one pulsed load, the controllable-field induction electrical machine configured to suppress one or more propulsion current harmonics generated by the propulsion converter that affect the at least one pulsed load.
