る突入電流防止回路。[Claim for Utility Model Registration] A device that converts AC voltage into DC voltage, consisting of a diode bridge, a capacitor, a thyristor, and a resistor, so that charging current flows through a resistor when the power is turned on and through a thyristor during steady state. In a rush current prevention circuit consisting of a rectifier circuit, a gate control circuit that controls ON/OFF of the thyristor, and a power supply circuit that supplies voltage to the gate control circuit, the gate control circuit has a resistor of the power supply circuit. A time constant circuit consisting of a resistor and a capacitor that obtains a voltage from the connection point of the Zener diode and determines the timing at which the transistor is turned on; a Zener diode that determines the voltage level at which the transistor is turned on; and a collector resistor for limiting the flowing current, and the power supply circuit is configured by connecting a resistor and a Zener diode in series between the output terminals of a diode bridge. Current prevention circuit.
