PROBLEM TO BE SOLVED: To obtain the new power source circuit which can remove the influence of a surge on a load when turned on and off. SOLUTION: A power source stabilizing circuit 103 is a circuit which stabilizes the source voltage supplied form the power circuit 101 with a reference voltage value and then outputs it. An operational amplifier, etc., is used for the power source stabilizing circuit 103, so the output state becomes unstable at the time of source voltage application and a surge is generated in the output. A switch 104 serves to stop the surge generated when the power source stabilizing circuit 103 enters a steady state from being supplied to the load. A switch 102 functions to prevent the power source stabilizing circuit 103 from turning on in the unstable state. The times for which the switches 102 and 104 are turned 'ON' are controlled to apply a surge-free stabilized voltage to the load. |
