Title: POWER SUPPLY SYSTEM
Abstract:
A power supply system (1A) is provided with: converter units (10a-10c) for generating a direct-current voltage Vout1 upon receiving an alternating-current voltage supplied from an alternating current power supply; and a rectifying/smoothing unit (20) for generating a direct-current voltage Vout2 by rectifying and smoothing an alternating-current voltage. The converter units (10a-10c) and the rectifying/smoothing unit (20) are connected in parallel. In a case where an output current of the converter units (10a-10c) is less than a threshold value, the direct-current voltage Vout1 is higher than the direct-current voltage Vout2. Thus, a power supply system having a redundant configuration allows increase of cost to be inhibited and allows the space for a power supply circuit to be reduced.
