流電源装置。 In a DC power supply device that switches the rectification method according to the level of input voltage, there is a determination means for determining whether the input voltage is high or low, and the rectification method is changed to full-wave rectification or voltage doubler according to the high or low input voltage determined by the determination means. A switch means for switching to rectification, a bypass means connected in parallel to the switch means, and a signal for switching the switch means from voltage doubler rectification to full-wave rectification when the input voltage changes from low voltage to high voltage, simultaneously switching the bypass means. 1. A direct current power supply device comprising: drive means for outputting a drive signal.
