Title:
CURRENT SENSOR AND ELECTRIC POWER CONVERSION CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2021/085475
Kind Code:
A1
Abstract:
This current sensor comprises: an element that is in a high-resistance state when the absolute value of current flowing between a first end and a second end is within a first range, the element changing to a low-resistance state having a lower resistance value than in the high-resistance state when the absolute value of the current exceeds the first range 50; and a circuit that supplies current to be measured to the element and senses the value of the current to be measured on the basis of the voltage of the first end and/or the second end.
