When you get the call, “The motor won’t start,” you’d best have a logical and systematic plan in place to approach the problem. “Easter egging” just doesn’t work unless you happen to be very lucky!

Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

See Part 1, Part 2, and Part 3 of this series. The previous FET circuits pertained to voltage-controlled signal amplitude circuits. That is, the input signal’s amplitude can be changed at the output ...

The circuit has been designed for the purpose of creating a portable unit of preamplifier that would function as standalone control for gutitars. TL062 – a low power JFET dual operational amplifier ...

A ripple-generating circuit is usually needed to ensure stability of constant-on-time (COT) controlled buck converters. Different values of the ripple generating circuit can have direct impacts on ...

Nestled inside a wound, a remote-controlled device perks up and begins releasing bacteria-killing heat, a form of thermal therapy that can fell even the most drug-resistant microbes. After it does its ...
