Title:

POWER FEED CONTROL DEVICE

Document Type and Number:

WIPO Patent Application WO/2017/110878

Kind Code:

A1

Abstract:

In a power feed control device (11), a control circuit (23) adjusts a resistance value between the drain and the source of a semiconductor transistor (20) by adjusting a gate voltage of the semiconductor transistor (20). After the control circuit (23) reduced the resistance value between the drain and the source, a control unit (56) determines whether a source voltage detected by a voltage detection unit (21) is equal to or higher than a reference voltage. In the cases where it is determined that the source voltage is equal to or higher than the reference voltage by the control unit (56), the control circuit (23) reduces the resistance value between the drain and the source again. In the cases where it is determined that the source voltage is lower than the predetermined voltage by the control unit (56), the control circuit (23) adjusts the resistance value between the drain and the source to a resistance value equal to or higher than the resistance value obtained at a time when the determination was performed.
