Title:
POWER SUPPLY SWITCHING DEVICE, ROBOT, METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/246123
Kind Code:
A1
Abstract:
Achieved is a device and method that can execute a power supply switching process and a charging process without stopping power supply to a load. The device has: a first switching circuit that is provided between a first power supply port and a load to which a power is to be supplied; a second switching circuit provided between a second power supply port and the load; and a controller that controls each switching circuit. The controller causes each switching circuit to execute switching processes of three states including (a) an ON state, (b) an OFF state, and (c) a diode operation state in, and to execute a switching process of a power source connected to each power supply port without stopping power supply to the load. Furthermore, a battery is charged by regenerative energy generated by the rotation of the motor that is a load.
