Title
(EN) METHOD FOR DETECTING POWER CABLE STATE IN INVERTER SYSTEM
(KO) 인버터 시스템에서 전력 케이블의 상태 검출 방법
Abstract
(EN)
A method for detecting the state of a power cable in an inverter system according to an embodiment of the present invention comprises the steps of detecting a voltage value of a DC stage for a DC stage capacitor which is included in an inverter; detecting a voltage value of a battery for supplying DC power to the inverter; comparing the voltage value of the DC stage and the voltage value of the battery; and determining that the state of the power cable connecting between the inverter and the battery is in an abnormal state if a difference value between the the voltage value of the DC stage and the voltage value of the battery goes beyond a preset range.
