Abstract

PURPOSE: To preclude an electric shock accident in repairing operation for a commercial power failure detecting the power commercial failure from the drop of active power to zero and disconnecting the commercial power source from a converting circuit.
CONSTITUTION: When the power failure occurs to the commercial power source 1, the electric power which is supplied from the side of the commercial power source 1 so far is not supplied, so the output of an active power detector 7 can not be held plus. At this time, the output of the detector 7 shifts from a plus value to zero. The detector 7 itself detects this variation and sends its detection signal to a comparator 71, which recognizes the occurrence of the power failure to open an exception switch 3, which disconnects the commercial power source 1 from the converting circuit 2 and isolates it from a solar battery 6. Consequently, even if the solar battery 6 continues to generate electric power during the repair of the commercial power source 1, there is no danger of an electric shock.
