Current controller, switch controller, current control method and computer program

摘要

PROBLEM TO BE SOLVED: To provide a current control device, a switch control device, a current control method and a computer program capable of matching a constant current drawn by a constant current circuit with a set value set by a processing unit. A current control device includes a constant current circuit 30 and a current regulator 31. The current regulator 31 applies a voltage to the constant current circuit 30. The constant current circuit 30 draws a constant current according to the applied voltage. The microcomputer 50 sets the value of the constant current drawn by the constant current circuit 30, and adjusts the voltage applied to the constant current circuit 30 by the current regulator 31 to a voltage corresponding to the set set value. The microcomputer 50 adjusts the voltage applied to the constant current circuit 30 by the current regulator 31 based on the difference value between the constant current drawn by the constant current circuit 30 and the set value.
