Title:
SWITCHING CIRCUIT, DC POWER OUTPUT DEVICE, WIRELESS POWER TRANSMISSION SYSTEM, PHOTOVOLTAIC GENERATION SYSTEM, OUTPUT CONTROL METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/188898
Kind Code:
A1
Abstract:
Provided are: a switching circuit which can suppress reduction in output power even when power generated from a plurality of DC power source circuits changes; and a DC power output device, a wireless power transmission system, and a photovoltaic generation system having said switching circuit. A connection circuit unit of the switching circuit has a plurality of switches that are provided between: a plurality of plus input units and a plurality of minus input units; and a plus output unit and a minus output unit. The plurality of switches can perform on/off control so as to switch the connection state between: the plurality of DC power source circuits; and the plus output unit and the minus output unit.
