From your very first blinking LED to dazzling multi-color sequences, Arduino makes it easy to bring light to life. With just a board, a few LEDs, and some code, you can experiment with patterns, ...

Switching has almost always meant “hard" switching, which is simple but comes with all kinds of electrical and thermal stresses. Soft switching employs more sophisticated design to reduce stresses and ...

Louise Tumchewics, visiting fellow at the University of Southern Denmark, talks to PWM about great power competition and its geoeconomic impact on portfolios and the services of tech-led wealth ...

An AC/DC power supply with input power greater than 75 W requires power factor correction (PFC) to: Take the universal AC input (90 V to 264 V) and rectify that input to a DC voltage. Maintain the ...

Abstract: In this article, a time-symmetric sampling method is proposed to eliminate the pulse-width-modulation (PWM) delay in digital PWM (DPWM) inverters. To attain this objective, an analysis of ...

Full-wave rectifies mains signal and compares it to a near-ground VDC signal to produce a 'zero' crossing signaling pulse. Comparison yields a current-sinking pulse, normally high. Pin D3 receives a ...
