ことを特徴とするＤＣ／ＤＣコンバータ。 A DC/DC converter that transforms and controls direct current input, converts it into stabilized direct current, and outputs it, comprising a control section, a starting circuit for the control section, and a switching means for controlling the output voltage based on a signal from the control section. a first smoothing circuit interposed between the switching means and the output side; and a second smoothing circuit interposed between the switching means and the control section, the control section 1. A DC/DC converter, characterized in that after being started by a starting circuit, a power supply voltage for the control section is supplied via the switching means and the second smoothing circuit.
