This article brings control theory to life. Too often control theory is taught using block diagrams with no reference to real ...

Electrical circuits have always been a mystery to me. Those tiny components that look like Chiclets or jewelry beads somehow make a light blink, produce music, and detect motion. So I was happy to ...

Electronic ballasts for fluorescent lighting deliver high efficiency and long lamp lifetimes. A new and simplified control circuit demonstrates complete control of the ballast, including all necessary ...

Although the design of this simulator has been reduced to the essentials, this powerful electronic circuit simulator offers a wealth of possibilities. Not only does it offer almost 200 circuits ...

In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...

The circuit was constructed with the use of power audio amplifier LM380 in conjunction with the circuit that makes use of electronic soft switching and tone control. The circuit was constructed with ...

The diagram above is a typical PCB layout in Altium Circuitmaker software. The days of “electro” and “mechanical” being separate disciplines are long gone. Virtually all mechanical systems now come ...

An international group of researchers has developed an electronic device that is said to effectively mitigate hotspots in PV modules. It uses two current comparators, two NPN transistors, and a ...
