Title:
POWER FEED CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/107572
Kind Code:
A1
Abstract:
A power feed control device (11) controls power feeding through an electrical wire (W1). A first current output circuit (21) outputs a larger current to a temperature difference circuit (24) as an electrical wire current flowing through the electrical wire (W) becomes larger. The temperature difference circuit (24) outputs a higher voltage as a temperature difference between the electrical wire temperature of the electrical wire (W) and the environmental temperature around the electrical wire (W) becomes larger. A drive circuit (28) cuts off conduction of the electrical wire current when the output voltage of the temperature difference circuit (24) becomes equal to or higher than a voltage threshold.
