ABSTRACT:
A DC voltage converting device having a choke coil, a switching device, a capacitor for accumulating electric energy, an inhibition setting device for setting and releasing an inhibition of charging, a current detecting device for detecting a charge current of the choke coil, a charge/discharge setting device for setting a discharge of the choke coil, and a driving device for conductively energizing the switching device. Based on this construction, when a capacitor voltage exceeds a predetermined voltage, only a time for interrupting the charge is extended.
