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 8):
The power supply device according to  claim 4 , where the current controlling circuit further comprises:\n a second raising circuit that raises the reference voltage with a capacity lower than a voltage lowering capacity of the lowering circuit; a logical module that permits the second raising circuit to raise the reference voltage after a term during which the current detecting voltage does not fall below the first divided voltage exceeds a predetermined term; and a second voltage divider circuit that divides the reference voltage to generate a second divided voltage higher than the first divided voltage; and a third comparator that compares the second divided voltage with the current detecting voltage, wherein the logical module allows the second raising circuit to raise the reference voltage based on the result of comparison by the second comparator and the result of comparison by the third comparator after the current detecting voltage falls below the second divided voltage and after a term during which the current detecting voltage does not fall below the first divided voltage exceeds a predetermined term.
