To provide a method for protecting an electric propulsion system in response to occurrence of a fault.SOLUTION: The method includes the step of activating short circuits in power switches of inverters (14a and 14b) in a motor controller (50) to redirect current regenerated by a motor (30) which is electrically coupled to the motor controller (50) and mechanically coupled to a propeller (32). The method further includes feathering the propeller (32) while the motor (30) is regenerating current. The protection logic is designed to address different types of faults, including faults in the high-voltage direct-current bus, faults in the motor controller (50), and faults in the motor (30).SELECTED DRAWING: Figure 2

    【課題】故障の発生に対応して電動推進システムを保護するための方法を提供する。【解決手段】方法は、モータコントローラ(50)に含まれるインバータ(14a、14b)の電力スイッチを短絡させるステップを含み、これによりモータコントローラ(50)に電気的に接続されているとともにプロペラ(32)に機械的に接続されているモータ(30)によって生成される回生電流の経路を変える。さらに、モータ(30)が回生電流を生成する間に、プロペラ(32)をフェザリングすることを含む。保護ロジックは、高電圧直流バスにおける故障、モータコントローラ(50)における故障、及びモータ(30)における故障を含む様々な種類の故障に対応する。【選択図】図2
