PROBLEM TO BE SOLVED: To prevent, for example, the occurrence of drops of an input voltage and an output voltage of an inverter circuit at the time of starting self-output.SOLUTION: An inverter device includes an inverter circuit 20, a relay contact 31, a line-filter circuit 40, and a control section 70 controlling the inverter circuit 20 and a relay coil 30. The control section 70 outputs control signals S11 to S16 on the basis of a voltage detection signal SV20 of an output voltage from the inverter circuit 20 and a current detection signal SI20 of an output current from the inverter circuit 20, and performs control of soft-start that moderately starts up an output voltage V20 of the inverter circuit 20. Upon determining that the output voltage V20 reaches a rating voltage after the completion of the soft-start, the control section 70 outputs a control signal S17 to turn on the relay contact 31 after a predetermined time. |
