とする整流回路。[Scope of claim for utility model registration] A rectifier that rectifies AC power and outputs it to a DC bus, a smoothing capacitor that is connected between the DC buses and smoothes the output of the rectifier, and an inrush capacitor that suppresses inrush current when AC voltage is applied. The inrush current suppressing circuit includes a current suppressing resistor, and both ends of the current suppressing resistor are normally open.
A rectifier circuit comprising a switch that shorts when AC power is applied, wherein the inrush current suppression circuit is connected in series with a smoothing capacitor between DC bus bars. .
