Beschreibung
Zusammenfassung:	The present invention relates to an initial charging circuit of an inverter which connects a measurement resistor to a relay driving coil in series, wherein the measurement resistor can measure a coil excitation current of a relay driving circuit to determine whether a relay of the initial charging circuit of the inverter is out of order, and determines whether the relay driving circuit is normal by a voltage applied to the measurement resistor to decide whether the inverter is operated, thereby preventing malfunction of the initial charging circuit of the inverter or malfunction of the entire inverter. 본 발명은 인버터의 초기충전회로에 관한 것으로, 인버터 초기충전회로의 릴레이 고장여부를 판단하기 위해 릴레이 구동회로의 코일 여자전류를 측정할 수 있는 측정저항을 릴레이 구동 코일과 직렬로 연결하고 측정저항에 걸리는 전압에 의해 릴레이 구동회로의 정상여부를 판단하여 인버터의 동작여부를 결정함으로써 인버터 초기충전회로의 고장이나 인버터 전체의 고장을 방지할 수 있는 효과가 있다.
