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, ...

Designed for EVs and HEVs, these current sensors deliver accurate, isolated measurement for batteries, motors, and safety ...

Members can download this article in PDF format. High-voltage systems including electric vehicles, industrial robots, communications infrastructure equipment, and renewable-energy installations often ...

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 ...

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) ...

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 ...

Littelfuse has introduced a new range of automotive-qualified current sensors aimed at improving the performance, efficiency, ...

A common data logging application is measuring voltage or current flowing into or out of a piece of equipment, such as a user monitoring current in solar cells, inverters, or storage batteries. These ...

As previously mentioned, the feedback sensors include position sensors to track the rotor’s location, current sensors to measure the motor phase currents, voltage sensors to monitor the DC bus voltage ...

Graphene-based Hall sensors represent a significant advancement in magnetic field measurement by harnessing the exceptional electrical and mechanical properties of graphene. Owing to its atomically ...
