In Part 1 of this five-part series, we examined FET voltage controlled resistors, basic voltage controlled resistor circuits, and a balanced or push pull voltage controlled resistor (VCR) circuit.

The power converter has high-voltage and high-current switching waveforms that generate electromagnetic interference (EMI) in the form of both conducted The power converter has high-voltage and ...

Bob and Tim are discussing the job that they are about to start. They are at a residence and the system has a blown low-voltage fuse. Tim said, “Let’s just change the fuse and try it and see if the ...

Voltage clamps for protecting low-voltage dc circuits require a new approach to circuit design. Many commonly used voltage clamps were built for systems of 5 V or higher, but lower-voltage systems ...

H-bridge buck-boost ICs are widely used in applications requiring a constant voltage or current source even when the system battery drops to lower voltages. They make sense when a single-stage ...

Courtesy of www.MikeHolt.com. Based on the 2020 NEC. Article 725 of the National Electrical Code (NEC) covers remote-control, signaling, and power-limited circuits that are not integral to a device or ...

I see techs in the field get the most frustrated when they have a low-voltage short they can’t seem to locate. The challenge techs face with low voltage diagnosis is a combination of poor process and ...

This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...
