Abstract
A power supply device according to an embodiment may include: a voltage generator configured to generate, from a commercial power supply, a first voltage and a second voltage lower than the first voltage; a voltage step-down part configured to decrease the first voltage to the second voltage; a bypass part configured to output the second voltage output from the voltage generator, with the voltage step-down part bypassed; and a controller configured, in a normal operation mode, to cause the voltage generator to generate and output the first voltage and to cause the voltage step-down part to operate and decrease the first voltage to the second voltage and output the second voltage, and configured, in a power-saving mode, to cause the voltage generator to generate the second voltage and output the second voltage through the bypass part without causing the voltage step-down part to operate.
