Included among the many applications for pulse-width modulation (PWM) are voltage regulation, power-level control, and fan-speed control. A PWM circuit for such systems can be implemented with three ...

Why PWM? Switch-mode converters employ a power semiconductor switch (usually a MOSFET) to drive a magnetic element (transformer or inductor) whose rectified output produces a dc voltage. Efficiencies ...

Pulse Width Modulation or PWM technology is used in Inverters to give a steady output voltage of 230 or 110 V AC irrespective of the load. The Inverters based on the PWM technology are more superior ...

Here this circuit is based on the principle of audio amplification using operational amplifier and pulse width modulation using 555 Timer. In this article we are describing the principle, design and ...

Continental has been granted a patent for a method of switching electronic components using pulse-width modulation signals. The method controls output signals through control signals, adjusting them ...

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 ...

Researchers from the University of Sistan and Baluchestan, in Iran, have suggested a new strategy to mitigating the risk of voltage spikes in the power electronics of small scale generation systems.

[Michael Kleinigger] posted a lengthy discussion on Pulse-Width Modulation that goes beyond the traditional beginner tutorial. He starts a bit of background info on PWM and a tip about using a camera ...
