Abstract

A propulsion system (20) includes a propulsor (26), an engine (22), an electrical assembly (24), and a protection circuit. The engine (22) is coupled with the propulsor (26). The electrical assembly (24) includes a battery (66), a motor control unit (64), an electric motor (62), and an electrical distribution system (68). The electrical distribution system (68) is configured to electrically interconnect the battery (66) and the motor control unit (64). The electrical distribution system (68) includes a contactor between the battery (66) and the motor control unit (64). The motor control unit (64) is electrically connected with the electric motor (62). The electric motor (62) is coupled with the propulsor (26). The protection circuit includes a current sensor configured to measure an electrical current between the battery (66) and the motor control unit (64). The protection circuit is operable to identify a reverse current flow using the measured electrical current and transmit a protection open control signal to the contactor to control the contactor to switch to an open state.
