[esot.eric] was trying to drive a motor and naturally thought of using pulse width modulation (PWM) to control the motor speed. However, he found that even with a large capacitor, his underpowered ...

Cyanobacteria, an ancient lineage of bacteria that perform photosynthesis, have been found to regulate their genes using the ...

PDM — pulse density modulation — is similar to PWM and, like PWM, requires a filter that could range from a simple RC network to an active filter. You can see the result in the video below.

Scientists in the Emirates have conceived a new space vector pulse width modulation method that reportedly reduces switching losses and increase efficiency in three-phase photovoltaic inverters.

Dolphin Technology provides Pulse Width Modulator (PWM) IP which can easily modify the shape of the waveform during operation, adjusting both the period and high time through an AMBA® APB slave ...

“By using pulse shaping you can create the type of modulation you need with a single pulse [from a single laser],” Serati says. Pulse shaping can also be used to generate point-source X-rays ...

The development of solid-state motor drive packages over the last 30 years has revolutionized the application of electric motors. Any power control problem can be solved using them. The solid-state ...
