Scalable power distribution system and method

A scalable power distribution system for receiving input power of one of plural types and providing output in a plurality of voltage ranges, comprising:

• a power distribution device, comprising:
• a plurality of input modules, wherein each of the plurality of input modules comprises a connector, and the connector is configured to receive the input power and is electrically connected to at least a neighboring input module among the plurality of input modules;
• and
• a plurality of output modules, electrically connected to the plurality of input modules respectively, wherein each of the plurality of output modules has a plurality of output ports, each of the plurality of output modules is configured to receive the input power from the connector of a corresponding input module among the plurality of input modules, or receive the input power from the connector of a neighboring input module neighboring to the corresponding input module, and each of the plurality of output modules is configured to output an output power according to the input power,
• wherein each of the plurality of input modules is configured to adaptively receive the input power chosen from one of the plural types, and the power distribution system is configured to selectively receive one or more times of the input power through one or more of the plurality of input modules to provide one or more times of the output power to one or more of the output ports.
