PROBLEM TO BE SOLVED: To provide a stop circuit of an inverter circuit capable of reducing the impact of stopping the inverter circuit on a power system, where a plurality of inverter devices are connected in parallel.SOLUTION: A stop circuit of an inverter circuit includes a timing phase creation section 71 for creating a timing phase &thetas;synchronized with other stop circuit 7, a delay section 73 for delaying the timing phase &thetas;by a predetermined value, and a stop signal output section 74 outputting a stop signal for stopping an inverter circuit 2, at a timing corresponding to a timing phase &thetas;' outputted from the delay section 73. Since the stop circuit 7 outputs a stop signal at a timing different from other stop circuit 7, even if the timing of outputting a detection signal from a protection circuit 6 is the same, the stop timing of the inverter circuit 2 is also different from the timing of other inverter circuit 2. Consequently, the impact of stopping a distributed power supply A on the power system can be reduced. |
