Power fusion system for supply and demand disparities

A power supply device, comprising

• a power fusion system and a distribution box;
• the power fusion system coupled to the distribution box;
• and
• the power fusion system comprising a control unit,
• at least one power conversion unit, and
• a DC/AC unit, wherein
• the power conversion unit is configured to convert current output by at least one power supply into DC;
• the DC/AC is unit coupled to all of the at least one power conversion unit, and is configured to convert DC output by the at least one power conversion unit into AC that meets a power supply demand;
• the control unit communicates with all of the at least one power conversion unit and the DC/AC unit and is configured to control operation of the at least one power conversion units and the DC/AC unit;
• and
• the distribution box is configured to determine the power supply demand and allocate the at least one power supply coupled with the power fusion system to supply power to a load according to the power supply demand.

A power supply system, comprising

• a distribution box, a power fusion system, and at least one battery module;
• wherein
• the distribution box is coupled with the power fusion system and the battery module;
• the power fusion system comprises
• a control unit, at least one power conversion unit, and a DC/AC unit;
• the power conversion unit is configured to convert current output by a power supply into DC;
• the DC/AC unit is coupled with all installed power conversion units and is configured to convert DC output by one or more power conversion units into AC that meets power supply demand;
• the control unit communicates with all installed power conversion units and the DC/AC unit, and is configured to control operation of one or more of the power conversion units and the DC/AC unit;
• the distribution box is configured to determine power supply demand and allocate the power supply connected with the power fusion system according to the power supply demand;
• and
• the battery module supplies power to the load separately or jointly.
