PWM Full Form In English
PWM, or Pulse Width Modulation, is a widely used technique in electronics and electrical engineering. It controls the amount of power delivered to electrical devices by varying the width of the pulses in a pulse train while keeping the frequency constant. PWM is commonly used in applications like motor speed control, LED dimming, and voltage regulation because it is energy-efficient and provides precise control.
