源装置。In a power supply device that applies DC voltage to a load by sequentially valving a smoothing circuit having a switching transistor, a choke coil, and a capacitor, the power supply device includes a differential amplifier that outputs the difference between a set output voltage and an output voltage to the load, and a choke coil. A current detector converts the current flowing into a voltage corresponding to this current value, and a comparator that compares the output voltage of the differential amplifier and the output voltage of the current detector. A power supply device characterized in that it is controlled.
