発明の名称 (英語) CURRENT SENSOR AND ELECTRIC POWER CONVERSION CIRCUIT
発明の概要(英語) 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.
従来技術、競合技術の概要(英語) BACKGROUND ART
A current sensor is known that senses a current by sensing both ends of a resistor through which the current flows (e.g., NpL 1). It is known that, in a detector that detects current using an on-resistance of an FET (Field Effect Transistor), the measurement range is switched by switching the voltage applied to the gate of an FET (for example, Patent Document 1).
