PWM Meaning and
Definition
-
PWM stands for Pulse Width Modulation. It is a digital technique that is used to control the amount of power delivered to electrical devices such as motors, LEDs, and speakers. PWM works by quickly switching the power supply on and off, with varying pulse widths, to regulate the average power delivered to the load.
In PWM, the width of each pulse is modulated or varied to control the average power. The width of the pulse, also known as the duty cycle, determines the amount of time the power supply remains on during each cycle. For example, a pulse with a 50% duty cycle would have its power supply on for half of the time and off for the other half.
This modulation technique allows for precise control over the power delivered to a load. By altering the duty cycle, the average voltage or current supplied to the load can be adjusted. This enables efficient control of the speed of a motor, the brightness of an LED, or the volume of an audio output.
PWM is widely used in various industrial and consumer electronics applications. One of its notable advantages is its ability to efficiently control power delivery while minimizing overall power consumption. Additionally, its digital nature makes it easy to implement using microcontrollers or dedicated PWM controller chips.
