PWMcontrollers
A PWM controller, or Pulse Width Modulation controller, is an electronic device used to regulate the output power delivered to a load by switching the power supply on and off at a high frequency. The "width" of the pulse, meaning the duration for which the power is on relative to the total cycle time, is varied to control the average power delivered. This allows for a wide range of power output from a fixed voltage source.
The fundamental principle behind PWM is the rapid switching of a power semiconductor device, such as a
PWM controllers are widely used in various applications due to their high efficiency and precise control. Common
