Zusammenfassung:	The present invention relates to a method for controlling a relay for preventing relay damage due to an inrush current. In the method for controlling a relay which connects or block a system and an inverter, the method for controlling a relay according to an embodiment of the present invention includes the steps of: turning on the relay; measuring a voltage provided from the system to the inverter; turning off the relay which is turned on based on the measured voltage; re-measuring the voltage provided from the system to the inverter; and turning on the relay which is turned off based on the re-measured voltage. 본 발명은 돌입 전류에 의한 릴레이 손상을 방지하기 위한 릴레이의 제어 방법에 관한 것이다. 본 발명의 일 실시예에 따른 릴레이의 제어 방법은, 계통과 인버터를 연결 또는 차단하는 릴레이의 제어 방법에 있어서, 릴레이를 턴온(turn-on)시키는 단계, 계통에서 인버터로 제공되는 전압을 측정하는 단계, 측정된 전압을 토대로 턴온된 릴레이를 턴오프(turn-off)시키는 단계, 계통에서 인버터로 제공되는 전압을 재측정하는 단계 및 재측정된 전압을 토대로 턴오프된 릴레이를 턴온시키는 단계를 포함한다.
