Disclosed is an inverter. According to an embodiment of the present invention, the inverter comprises: a scale unit adjusting a level of DC link voltage of an inverter; a proportional integral (PI) control unit performing PI control on an error of the output of the scale unit and the output voltage of the inverter, and outputting a control signal; a first calculation unit summing a command frequency of the inverter and the control signal; and a voltage determination unit determining the output voltage of the inverter from an output frequency of the first calculation unit.

    인버터가 개시된다. 본 발명의 일실시예의 인버터는, 인버터의 DC링크 전압의 크기를 조절하는 스케일부, 상기 스케일부의 출력과 인버터 출력전압의 오차를 비례적분(PI) 제어하여 제어신호를 출력하는 PI 제어부, 상기 인버터의 지령주파수와 상기 제어신호를 합산하는 제1연산부, 및 상기 제1연산부의 출력주파수로부터 인버터의 출력전압을 결정하는 전압 결정부를 포함한다.
