Abstract

The embodiment of the invention discloses a power supply device and a power supply system, which are used for reducing the size and cost of the power supply device. The power supply device comprises aswitching circuit which comprises a switcher, a first input end, a second input end and an output end. The first input end of the switching circuit is used for receiving a first voltage provided by afirst power supply. The second input end of the switching circuit is used for receiving a second voltage provided by a second power supply. The switcher is used for controlling the output end of theswitching circuit to be connected with the first input end or controlling the output end of the switching circuit to be connected with the second input end. The power supply device further comprises aconversion circuit which comprises an input end and an output end. The input end of the conversion circuit is connected with the output end of the switching circuit, and the output end of the conversion circuit is connected with electric equipment. The conversion circuit is used for receiving the first voltage or the second voltage, converting the received first voltage or the received second voltage into a third voltage and outputting the third voltage through the output end of the conversion circuit.

Description

technical field [0001] The present application relates to the technical field of power electronics, and in particular to a power supply device and a power supply system. Background technique [0002] Distributed data center computer rooms have very high requirements for power supply reliability. Each electrical device usually needs to be equipped with a dual-circuit power supply for power supply. The power supply method is mostly uninterruptible power supply (UPS, uninterruptible power supply) power supply or high-voltage direct current transmission (HVDC) powered by. [0003] A typical distributed data center power supply architecture is powered by two UPSs, two HVDCs, or a mix of UPS and HVDC. For the loads in the data center computer room, each UPS or HVDC is equipped with a power module for each load and connected to the load to realize mutual backup. It can be seen from this that in the prior art applications that require high power supply, two power supplies are equi...
