Pulse-width modulation (PWM), or pulse-duration modulation (PDM), is a method of controlling the average power delivered by an electrical signal. The average value of voltage (and current) fed to the load is controlled by switching the supply between 0 and 100% at a rate faster than it takes the load to change … See more The term duty cycle describes the proportion of 'on' time to the regular interval or 'period' of time; a low duty cycle corresponds to low power, because the power is off for most of the time. Duty cycle is expressed in … See more Pulse-width modulation uses a rectangular pulse wave whose pulse width is modulated resulting in the variation of the average value of the waveform. If we consider a pulse … See more • Analog signal to discrete time interval converter • Class-D amplifier • Computer fan control See more The Corliss steam engine was patented in 1849. It used pulse width modulation to control the intake valve of a steam engine cylinder. A See more Servos PWM is used to control servomechanisms; see servo control.
