As engineers, you use many components and devicesevery day that you treat as black boxes. You are concernedonly about the inputs and outputs of the blackbox, and that approach is acceptable provided ...

This conference is co-located with other relevant conferences at the IDTechEx Show! Your conference pass allows you to access any conference sessions.

Pulse Width Modulation (PWM) or Pulse Duration Modulation (PDM) is a technique of converting analog signals into rectangular waveforms. The width of the waveform varies in proportion with the ...

The AMC6821 is an intelligent temperature monitor and pulse-width modulation (PWM) fan controller. It is designed for noise-sensitive or power-sensitive applications that require active system cooling ...

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 ...

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.

Some of the UK’s most serious sprayer operators are turning to pulse-width modulation (PWM) systems in a bid to improve accuracy and slash chemical costs, apparently unperturbed by its £25,000 price ...
