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) ...

Recently, I’ve been working on a solar off-grid monitoring system. In the system are a few split-core Hall effect sensors to monitor DC current in the solar panel current, the battery charge current, ...

The quantum Hall effect, a fundamental effect in quantum mechanics, not only generates an electric but also a magnetic current. It arises from the motion of electrons on an orbit around the nuclei of ...

Sensing current, especially in higher-voltage settings, is often a challenge. It’s generally more difficult than voltage sensing, as it is usually “invasive” and requires “breaking” into the ...

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 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 ...

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

This article provides an in-depth overview of the significance and recent advancements of graphene in Hall effect sensor application. How Do Hall Effect Sensors Work? Hall effect sensors are ...

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.
