Abstract
A propulsion system (100) comprises: a generator (30) driven by a shaft (22) of a thermal engine (20) and configured to generate electrical power; an induction motor (60) that is electrically coupled to the output of the generator (30) and is configured to generate a rotational output in response to electrical power provided by the generator (30); a generator control unit (40) that is configured to control an output voltage of the generator (30) to limit a current supplied to the induction motor (60) during start-up of the propulsion system (100); and a switch (50) that is electrically coupled between the generator (30) and the induction motor (60), wherein the switch (50) is controllable by the generator control unit (40).
