LED bulbs are more efficient than older incandescent or fluorescent bulbs, and can save you significant money. But why do ...

Abstract: Pulse width modulation (PWM) techniques are widely used to control the switching of semiconductors in power converters. This paper presents a comprehensive overview of PWM techniques for two ...

To solve this problem, this article proposes and implements a sigma-delta pulse increment modulation (PIM) of a full-bridge three-level flying-capacitor inverter for wireless power systems. The ...

Researchers in Iraq have designed a multi-level cascaded inverter that can purportedly produce high-quality sinusoidal output voltage and current waveforms, while reduing harmonic distortion. It uses ...

Smith was a featured guest speaker at NAB earlier that same morning. Scrolling through each day’s list of scheduled panels ...

In this paper, the performance of various Pulse Position Modulation (PPM) schemes has been analysed for PIN and APD receivers in the presence of atmospheric turbulence. It is observed that the ...
