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 ...

Recently, [Solder Hub] put together a brief video that demonstrates the basics of a Hall Effect sensor — in this case, one salvaged from an old CPU fan. Two LEDs, a 100 ohm resistor, and a 3.7 volt ...

If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds ...

As systems extend and expand the exploitation of the latest power semiconductors (IGBTs, MCTs, etc.) that manifest the very relentless advance in power output limits, a prerequisite (and parallel) ...

Motor control circuits in appliances including refrigerators, washing machines and air conditioners, need to operate more efficiently, reliably and safely while meeting cost requirements. With energy ...

High-voltage systems including electric vehicles, industrial robots, communications infrastructure equipment, and renewable-energy installations often require accurate current measurements. You can ...

What Is The Hall Effect? Discovered by Edwin Hall in 1879, the Hall effect is a phenomenon when voltage (potential difference) is generated across a current-carrying conductor when it is placed in a ...

The types of magnetic sensors that are currently available. How the magnetic sensors work. Applications for the different magnetic sensors. Position sensors enable a variety of functions and controls ...

Hall-effect magnetic field sensors measure ac and bidirectional dc with a minimum 800-V isolation. The ACS704 comes in a 1.7-mm-high SOIC8 package and is available in both 5 and 15-A versions.
