Title:
SWITCH CIRCUIT AND POWER SUPPLY CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2022/210273
Kind Code:
A1
Abstract:
This switch circuit is equipped with: a first switching element in which the connection state between a power generation element and a power storage device is controlled according to the voltage to be applied to a first control terminal; and a control circuit which outputs a first voltage for keeping the first switching element switched on to the first control terminal from when the voltage difference between ends of the power storage device is in an initial state until the voltage difference, which increases as time passes, reaches a first prescribed value which is larger compared to the initial state, and outputs a second voltage for keeping the first switching element switched off to the first control terminal from when the voltage difference exceeds the first prescribed value until the voltage difference falls below a second prescribed value which is smaller than the first prescribed value.
