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 ...

Sometimes a circuit requires a data link over an existing cable that doesn’t have any free conductors for a dedicated comm link. A common solution is to superimpose a high-frequency carrier modulated ...

Suspended ceilings in commercial buildings have grown in purpose and importance over the past few decades. At one time, they provided a grid for installing fluorescent troffers and created an overhead ...

In this post I will try to gain some insight into the electronics of a cheap PWM Power MOSFET Module. The module under the spotlight is the pretty common FR120N MOSFET Control Module which is a simple ...

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 ...

Ameren Transmission has energized the first two of four innovative upgrades to ensure its grid remains stable as the utility transitions to clean energy sources. Known as Static Synchronous ...
