PWMcontrolled
PWMcontrolled refers to systems or components whose operation is governed by pulse-width modulation (PWM). PWM is a modulation technique that adjusts the duty cycle of a fixed-frequency square wave to control the average power delivered to a load. By varying the proportion of time the signal is high within each cycle, PWM can regulate voltage, current, or power without changing the supply voltage.
In practice, a PWM-controlled device uses a switching element, such as a transistor, to rapidly turn between
Implementation methods include hardware PWM produced by microcontroller timers or dedicated PWM controllers, as well as
Advantages of PWM control include high efficiency, rapid response, and precise control over average load power.
