A wafer-thin flake of bismuth telluride can act a little like a one-way street for electricity, even when the push comes from an alternating signal. But the direction of that “street” is not fixed.

As power electronics switching techniques advance, there is an increased need to accurately measure current for feedback control and system monitoring. There are several methods to achieve this, and ...

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 ...

Scientists have pulled off a feat long considered out of reach: getting light to mimic the famous quantum Hall effect. In ...

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, ...

Most common types of EV current sensors. Some pros and cons of current sensing methods. Tradeoffs between different types of current sensing. Multiple points within an electric vehicle (EV) or hybrid ...

The newest current sensor family from Allegro MicroSystems, Inc., the ACS704, is the first SOIC8-packaged Hall-effect current sensor with the current path integrated into the package for greater ...

What is the Hall Effect? The Hall effect is a fundamental phenomenon in physics that occurs when an electric current flows through a conductor in the presence of a magnetic field perpendicular to the ...
