Title:
POWER FEEDING CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/131698
Kind Code:
A1
Abstract:
A power feeding control device (10) in which power feeding is controlled by switching on or off a first semiconductor switch (20a) and a second semiconductor switch (20b) that are arranged in a current path. A first diode (21a) and a second diode (21b) are connected between the drain and the source of the first semiconductor switch (20a) and the second semiconductor switch (20b), respectively. A cathode of each of the first diode (21a) and the second diode (21b) is positioned at the downstream side or the upstream side, respectively, of an anode in the current path. If current is flowing in the current path even though a microcomputer (26) has instructed that the first semiconductor switch (20a) and the second semiconductor switch (20b) are to be switched off, a first drive circuit (22a) switches the first semiconductor switch (20a) off.
