CURRENT SEONSOR WITH EHHANCED TOLERANCE OF ELECTROMAGNETIC WAVES

摘要

Disclosed is a current sensor used in an electric vehicle. The current sensor measures the direction and magnitude of a current by using the Hall effect in a non-contact manner, and delivers the measurement result to an electronic control unit. Also, the present invention sets a ground area only on the upper part or the lower part of the printed circuit board of a current sensor to enhance electromagnetic susceptibility. Therefore, the malfunction of the current sensor is prevented.
