Abstract

PURPOSE: To realize an effective power source control by using the simple auxiliary power source only for starting of the power circuit part and with use of the auxiliary power source for starting of the power circuit part when the power source part is OFF and with use of the voltage generated from the stabilized power source the power source part when the power source part is ON respectively.
CONSTITUTION: Power source part 2 is provided corresponding to plural units of constitution device 1 of the electronic computer and then controlled by power control circuit 3, and circuit 3 is controlled by system power control unit4. Then the electric generation circuit is installed between circuit 3 and part 2, and at the same time battery 6 is provided to circuit 3 via switch 8 as the auxiliary power source. And switch 8 is turned on to device 1 when stabilized part 2 is OFF to use battery 6 for starting of part 3; while the voltage generated from stabilized part 2 is used when part 2 is ON. At the same time, battery 6 is charged via rectifier 7. Thus, an effective power source control is ensured by using the simple auxiliary power source only when circruit part 3 is started.
