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 ...

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 ...

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 ...

Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...

Pulse width modulation (PWM) is a common technique for generating analog voltages from a digital device such as a microcontroller or FPGA. Most microcontrollers have dedicated PWM generation ...

Cooling fans are widely used and are extremely important in electronic devices, especially for those constantly running. That includes power supplies, servers, computers, and telecommunication ...
