PURPOSE: To effectively utilize the electric power supplied from a DC power source by eliminating the influence of a DC component superposed upon the output current of an inverter and to link the inverter with a commercial system, etc. CONSTITUTION: An inverter is provided with a DC component detecting circuit 16 which detects a DC component superposed upon the output current of an inverter as a voltage level signal which is proportional to the level of the DC component and has positive and negative polarities and a DC component suppressing means 22 which shifts the level of the output current of the inverter in the direction in which the DC current is offset on the voltage level signal from the circuit 16. |
