CURRENT SENSOR AND METHOD FOR MANUFACTURING SENSOR MODULE FOR USE IN CURRENT SENSOR |
摘要 |
A current sensor for outputting a detection signal corresponding to a current flowing through a bus bar. The current sensor includes a magnetic core that concentrates and amplifies magnetic flux generated by the current near a detection portion of the bus bar. A magnetic detection element detects the magnetic flux concentrated by the magnetic core and outputs an electrical signal corresponding to the detected magnetic flux. A signal processing circuit includes electronic components and processes the electrical signal output from the magnetic detection element to generate the detection signal. A lead frame holds the magnetic detection element and the electronic components. The magnetic detection element, electronic components, and lead frame are combined to form a single sensor module. The current sensor detects the current flowing through the bus bar with the sensor module and outputs the detection signal.
