Abstract

This electricity-generation system is provided with the following: a plurality of electricity-generation units (1000-1 to 1000-N) that wirelessly transmit generated electrical power via magnetic-field coupling between resonators; an AC combining unit (121) that combines AC energy outputted from an AC conversion / output unit in each electricity-generation unit and supplies said AC energy to an AC load; a DC combining unit (122) that combines DC energy outputted from a DC conversion / output unit in each electricity-generation unit and supplies said DC energy to a DC load; and an output control unit (130) that controls the output of each electricity-generation unit by sending control signals to an output switching unit in said electricity-generation unit on the basis of the power consumption of at least one of the AC load and the DC load.

Description

technical field [0001] The present invention relates to a power generation system that efficiently distributes electric power generated by a plurality of power generation units, and a wireless power transmission system. Background technique [0002] Conventionally, a power distribution system for distributing AC power and DC power to loads (electric appliances such as lighting) installed in buildings has been proposed. For example, Patent Document 1 discloses a power distribution system in which not only AC power but also DC power can be supplied by providing a terminal for outputting DC power to an AC power outlet installed on a wall or the like in a room. electricity. This power distribution system includes: a distribution board having a transformer and a rectifier; and an AC power outlet having a DC output terminal. The transformer transforms the 100V or 200V AC voltage into 6V, 3V, 1.5V AC voltage used by the AC load, and outputs it to the rectifier. The rectifier rec...
