Title:
CURRENT CONTROL DEVICE, SWITCH CONTROL DEVICE, CURRENT CONTROL METHOD, AND COMPUTER PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/192898
Kind Code:
A1
Abstract:
This current control device is provided with a constant current circuit (30) and a current adjustment device (31). The current adjustment device (31) applies a voltage to the constant current circuit (30). The constant current circuit (30) draws a constant current in accordance with the applied voltage. A microcomputer (50) sets a value for the constant current drawn by the constant current circuit (30), and adjusts the voltage applied to the constant current circuit (30) by the current adjustment device (31) to a voltage in accordance with the set value that has been set. The microcomputer (50) adjusts the voltage applied to the constant current circuit (30) by the current adjustment device (31) on the basis of a difference value between the set value and the constant current drawn by the constant current circuit (30).
