CURRENT MEASURING DEVICE USING A MAGNETICALLY SENSITIVE SENSOR FOR A POWER ELECTRONICS SYSTEM |
摘要 |
A current measuring device in a power electronics system includes at least one circuit board and an electrical conductor which is guided through a frame surrounding the circuit board. The current measuring device includes a soft magnetic core surrounding the insulation of the electrical conductor, which core is arranged in the frame. The soft magnetic core is open at one location. A magnetically sensitive sensor, in particular a Hall sensor, is arranged in the recess of the soft magnetic core surrounding the insulation of the electrical conductor in order to detect the magnetic field strength. |
