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 ...

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 ...

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 ...

The electronic devices we encounter all around us are driven and controlled by the flow of electrical current through electronic circuits. Each circuit is an arrangement of electrical elements ...

While DSPs are the primary controllers in uninterruptible power supplies (UPS) with power-factor correction (PFC), ac generation and battery management, microcontrollers serve secondary functions for ...

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 ...

An overload or short circuit in a fuse or mini circuit breaker can lead to undersupply or failure of an entire 24-V dc power-supply system. Selectivity protection using an electronic fuse offers a ...
