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 ...

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 ...

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 ...

LEM has introduced a unique current sensor for electric-vehicle (EV) battery management. Dubbed the Hybrid Supervising Unit (HSU), the device is the first on the market to integrate both shunt and ...

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, ...

While TMR works differently, it's a similar concept to Hall effect devices. When you move a TMR joystick, it moves a magnet ...
