A power supply system which connects a DC consumer to an AC supply includes an AC-DC converter and a UPS. The AC-DC converter has an input to which alternating current from the AC supply is applied and an output at which DC current is developed. The UPS has an input to which direct current from the AC-DC converter is applied and an output at which DC current is developed. The DC current developed at the output of the AC-DC converter and DC current developed at the output of the UPS are applied to the DC consumer selectively in parallel with each other or exclusively to each other.
