PURPOSE: To reduce information concerning starting conditions to be communicated between power supply equipments by feeding a single pulse produced from any one pulse generating circuit in a plurality of power supply equipments to the starting circuits of all the power supply equipments.
CONSTITUTION: An interruption self-hold circuit 14 and a starting circuit 16 for providing a starting signal to the interruption self-hold circuit 14 according to a single pulse fed from a pulse generating circuit 15 are provided. A single pulse produced from the pulse generating circuit 15 in any one of a plurality of power supply equipments 13-1-13-N is fed to the starting circuits 16 of all power supply equipments 13-1-13-N, and the starting switches 10 of the power supply equipments 13-1-13-N are turned ON sequentially. Since only the starting pulse is communicated as starting condition information between the plurality of power supply equipments 13-1-13-N, the circuitry can be simplified.
