Abstract
Provided is a method of detecting a state of a power cable in an inverter system. The method includes detecting a direct current (DC)-link voltage value of a DC-link capacitor included in an inverter, detecting a battery voltage value of a battery supplying a DC power to the inverter, comparing the DC-link voltage value with the battery voltage value, and determining the state of the power cable connecting the inverter to the battery to be abnormal when a difference between the DC-link voltage value and the battery voltage value is out of a preset range.
