Apparatus and method for predicting fault state of inverter

Disclosed are an apparatus and a method for predicting a fault state of an inverter. The apparatus for predicting the fault state of the inverter includes: the inverter converting DC power into AC power; a switching element provided in the inverter; and a controller extracting a fault sign factor based on an output signal output from the inverter and predicting a fault of the switching element based on the fault sign factor. 本发明公开种用于预测逆变器的故障状态的设备及方法。用于预测逆变器的故障状态的设备包括：逆变器，其将DC电源转换为AC电源；开关元件，其设置在逆变器中；以及控制器，其基于从逆变器输出的输出信号提取故障征兆因子并且基于故障征兆因子预测开关元件的故障。
