If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds deceptively simple. There’s a metal plate with current flowing across it in one ...

The technique is called high-side current sensing. However, measurements at that location are fraught with problems. Of primary concern is that the measurement is at main line voltage, a problem if ...

Now more than ever, permanent magnets and electromagnets play a critical role in today’s advanced applications. From high-performance electric motors to magnetic nano-machines and high-reliability ...

Two similar families of precision, analog-output current sensors use the Hall effect to measure tens of amps with low drift and high linearity while providing 3-kVrms galvanic isolation. Current ...
