[0001] The present invention relates to a power distribution system and a power distribution method, and more particularly to a scalable power distribution system and a power distribution method. [Background technology]

[0002] In the prior art, a power distribution system receives input power and provides output power to electronic devices such as servers, storage devices, or network equipment.

[0003] A conventional power distribution system has one input port and multiple output ports for receiving input power and outputting output power, respectively. However, because a conventional power distribution system has only one input port and can only accept a single type of input power, using different types of power requires different power distribution systems with input ports corresponding to the corresponding types. In other words, a single power distribution system cannot accommodate all types of power. Furthermore, because a conventional power distribution system has only a single input port with a limited input power range, the output power range is also limited. As a result, it is not possible to increase the number of electronic devices connected to the power distribution system.

[0004] Therefore, there is a need to provide a scalable power distribution system and method to overcome the shortcomings encountered in the prior art. Summary of the Invention [Problem to be solved by the invention]

Each input module 10 includes a connector 10a configured to receive input power and is electrically connected to at least one adjacent input module 10. The multiple output modules 11 are electrically connected to the multiple input modules 10, respectively. The output module 10 has multiple output ports 11a. The output module 11 receives input power via the connector 10a of the corresponding input module 10 or via the connector 10a of the input module 10 adjacent to the corresponding input module 10. The output module 11 outputs output power according to the input power. The input modules 10 are configured to adaptively receive multiple types of input power, and the power distribution system 1 selectively receives the input power one or more times via one or more of the multiple input modules 10 and supplies output power one or more times to one or more of the multiple output ports 11a. The multiple output ports 11a of the output module 11 are electrically connected to multiple external electrical devices, respectively, and the output module 11 supplies output power to the multiple external electrical devices via the output ports 11a. The external electrical devices may be, for example, but are not limited to, power supply units (PSUs), servers, or other electrical devices. In one embodiment, the number of the multiple input modules 10 is equal to the number of the multiple output modules 11. The number of the multiple input modules 10 and / or the multiple output modules 11 is determined by at least one factor including a user design, a maximum power requirement of an application scenario, specifications of the power distribution system 1, power specifications of the external electrical devices connected to the power distribution system 1, and power specifications of the input power.
