An inverter control device suppresses the deviation between a detection result of an output current of an inverter and an actual current. The current detection unit (7) detects a three-phase AC current output from or input to the inverter (3). An inverter control device (1) controls an inverter (3) on the basis of a current detection value of a detection result of a three-phase AC current given by a current detection unit (7) and a predetermined current command value. An inverter control device (1) corrects a current detection value so as to correct a detection error of a three-phase AC current generated by a delay time of a filter (72), which is a filter element included in a current detection unit (7).
本发明的逆变器控制装置抑制逆变器的输出电流的检测结果与实际电流的背离。电流检测部(7)检测从逆变器(3)输出或者输入至逆变器(3)的三相交流电流。逆变器控制装置(1)根据由电流检测部(7)给出的三相交流电流的检测结果的电流检测值和规定的电流指令值来控制逆变器(3)。逆变器控制装置(1)修正电流检测值,以修正因电流检测部(7)所具有的滤波要素即滤波器(72)的延迟时间而产生的三相交流电流的检测误差。
