A PWM (Pulse Width Modulation) controller is an electronic device or circuit that generates a digital signal to control the power supplied to a load, typically a motor, an LED, or another type of electrical device. PWM controllers are widely used in various applications where precise control of the average voltage or current delivered to the load is necessary.
