オードを接続したことを特徴とする直流電圧変換回路。A DC input power supply, a choke coil, and a chopping switch are connected in series, and the chopping switch is controlled intermittently by a self-excited oscillation control unit, so that the AC voltage induced in the choke coil is added to the input voltage, and the voltage is added to the input voltage by the rectifying and smoothing unit and the circuit. The boosted output is taken out as a DC boosted output via an operation control switch, and is applied to the chopping switch via a chopper control section consisting of a first Zener diode and a switching transistor. 1. A DC voltage conversion circuit, characterized in that a second Zener diode having a Zener voltage set higher than that of the first Zener diode is connected between the base of the switching transistor of the first Zener diode.
