A pulse signal is defined by its amplitude and pulse width. A periodic pulse train has a frequency (pulse repetition rate) and a duty cycle (ratio of pulse width to repetition period, varying between ...

[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 … ...

The widely used PWM technique may fallinto this category. Most engineers use it every day to drive avariety of devices, but only a few know why they use it andhow it works. A pulse signal is defined ...

Pulse-width modulation (PWM) Pulse width modulation (PWM) is a powerful technique for controlling analog circuits with a microprocessor’s digital outputs. Pulse-width modulation,as it applies to LED ...

Pulse Width Modulation is a topic that tends to give a lot of beginners trouble. [Daqq], whose nixie plasma ball we covered a few days ago, has a simple but effective PWM project that you should ...

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 ...

How pulse-width modulation (PWM) works with switch-mode converters. How PWM can be used in different power-switching applications. Switch-mode converters employ a power semiconductor switch ...

This can be done by a continuous linear regulation power supply or pulse width modulation (PWM). Linear regulation is generally inefficient and a requires a larger housing.
