Abstract
PURPOSE:To improve reliability by providing the second switching means to control the first switching means for AC input switching, and closing the first switch a certain time later than the closing of the second switch. CONSTITUTION:A power circuit is constituted of AC power 1, the first switch 2, a fuse 3, a rectifier 9, a thermistor 10, a transformer 11 for convertor, a switching transistor(Tr) 17 and etc., and the power is supplied to a load 30. And, the second switching means 34 to control the making and braking of the first switch 2 is provided. The resistance of the thermistor 10 is in a state of low resistance by self-heating, but even if the second switching means is turned ON again, the first switch 2 is turned ON with a certain time of delay. Therefore, when an applicable delay time is set to the time corresponding with the resistance recovery time of the thermistor 10, the fully rush current suppressing effect can be obtained.
