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 14):
A method for suppressing a ripple component in a power supply device including a voltage conversion circuit that generates a DC voltage from an AC power source and outputs the DC voltage to a pair of output terminals, the method comprising:\n driving a current controller that controls a current in a current path through which an output current flows; and suppressing the ripple component occurring in the output current, wherein the method further comprises: outputting a drive signal to the current controller such that a difference between a reference voltage and a current detecting voltage indicating a magnitude of the output current; comparing the current detecting voltage with a first divided voltage generated by division of the reference voltage and lowering the reference voltage if the current detecting voltage is lower than the first divided voltage; and comparing a predetermined reference voltage with 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 current path through which the output current flows, and raising the reference voltage if the voltage at the first potential point is higher than the reference voltage.
