Abstract:
A power supply device includes: a power supply circuit that converts an AC voltage into a DC voltage; and a control circuit that controls the power supply circuit, wherein the power supply circuit includes: a rectifying and smoothing circuit that rectifies and smoothes the AC voltage; a first voltage converting circuit that converts the voltage and outputs a first DC voltage; a second voltage converting circuit that switches the first DC voltage by a switching circuit to output a second DC voltage; a feedback circuit that detects and feeds back an output voltage of the first voltage converting circuit; and a selection circuit that switches a reference voltage of the feedback circuit, and the control circuit sets the switching circuit to be in a continuous connection state when a normal mode is shifted to a power saving mode and gradually switches the reference voltage.

Claim (Index 1):
A power supply device comprising:\n a power supply circuit that converts an AC voltage into a DC voltage; and a control circuit that controls the power supply circuit, wherein the power supply circuit includes:\n a rectifying and smoothing circuit that rectifies and smoothes the AC voltage; \n a first voltage converting circuit that converts the voltage rectified and smoothed by the rectifying and smoothing circuit and outputs a first DC voltage; \n a second voltage converting circuit that switches the first DC voltage by a switching circuit to output a second DC voltage lower than the first DC voltage; \n a feedback circuit that detects and feeds back an output voltage of the first voltage converting circuit; and \n a selection circuit that switches a reference voltage of the feedback circuit to decrease the first DC voltage of the first voltage converting circuit to a third DC voltage, and \n the control circuit sets the switching circuit to be in a continuous connection state when a normal mode is shifted to a power saving mode and gradually switches the reference voltage of the feedback circuit when the normal mode is shifted to the power saving mode.
