Abstract:
A power supply device includes a voltage conversion circuit, a current controller and a current controlling circuit. The voltage conversion circuit generates a DC voltage from an AC power source and outputs the DC voltage to a pair of output terminals. The current controller is disposed on a first current path through which an output current flows and controls the current in the first current path. The current controlling circuit drives the current controller so as to reduce a ripple component generated in the output current, based on (i) a voltage at a first potential point set on a path from an output terminal at a high-potential side of the voltage conversion circuit to the current controller in the first current path and (ii) a current detecting voltage indicating the magnitude of the output current.

Claim (Index 3):
The power supply device according to  claim 1 , wherein the current controlling circuit comprises:\n a voltage-retaining module that retains a reference voltage; a differential circuit that outputs a drive signal to the current controller so as to decrease a difference between the reference voltage and the current detecting voltage; a reducing circuit that reduces the reference voltage; a first voltage divider circuit that generates a first divided voltage generated at a predetermined division ratio from the reference voltage; and a first comparator that compares the first divided voltage with the current detecting voltage and allows the reducing circuit to lower the reference voltage if the first divided voltage is higher than the current detecting voltage.
