What is PWM? A Deep Dive into Pulse Width Modulation!
Pulse Width Modulation (PWM) is a crucial technique in electronics and electrical engineering used for controlling power efficiently. Whether it's adjusting LED brightness, controlling motor speed, or even handling digital signals in communication systems, PWM plays a vital role.
How Does PWM Work?
PWM operates by switching a signal between ON and OFF states at high speed. The key aspect of PWM is the "duty cycle," which determines how long the signal stays ON within one cycle. By adjusting this duty cycle, the amount of power delivered to a device can be controlled without wasting energy.
Applications of PWM
✔ Motor Control – Used in DC motors to regulate speed smoothly.
✔ LED Dimming – Allows precise brightness control without causing flickering.
✔ Audio & Signal Processing – Helps in modulation techniques for communication systems.
✔ Power Conversion – Used in switching power supplies for efficient energy management.
With its ability to provide precise control while minimizing energy loss, PWM is an essential concept in modern electronics.
