ュレータの突入電流抑制回路。A smoothing capacitor is used as a DC input from the DC main circuit that rectifies the AC current to a series circuit of a switching transformer and a switching element, and the switching element is periodically controlled on and off by a control circuit to control the output of the switching transformer. In a switching regulator that rectifies and smoothes and supplies stabilized DC power to a load, a parallel circuit of a resistor and a switching element is provided on the low voltage side of the DC main circuit to suppress inrush current to the capacitor, and the DC main circuit 1. An inrush current suppression circuit for a switching regulator, comprising a circuit that turns on the switch element when a DC voltage supplied from the control circuit to the control power supply of the control circuit is established.
