Disclosed is a method for controlling an inverter for driving a motor, capable of solving a phenomenon that an inverter is damaged by an electromotive force of the motor when electric connection between direct current power (DC) and the inverter is disconnected while the motor is driven. The method for controlling an inverter for driving a motor comprises the steps of: monitoring an electric connection state between a DC power device and an inverter; detecting disconnection of the electric connection state; and controlling a switching element to be turned on/off to limit voltage of a DC side of the inverter to be within a predetermined range when the electric connection state is disconnected.

    모터 구동 중 직류 전원과 인버터의 전기적 연결이 단절되는 경우 모터의 기전력에 의해 인버터가 소손되는 현상을 해소할 수 있는 모터 구동용 인버터 제어 방법이 개시된다. 상기 모터 구동용 인버터 제어 방법은, 직류 전원 장치와 인버터 사이의 전기적 연결 상태를 모니터링하는 단계; 상기 전기적 연결 상태가 단절된 것을 감지하는 단계; 및 상기 전기적 연결 상태가 단절된 것으로 감지된 경우, 상기 인버터의 직류측 전압을 소정 범위 내로 제한하도록 상기 스위칭 소자의 온/오프를 제어하는 단계를 포함한다.
