Pulse Width Modulation for Control and Automation

af Loganthan

Learn to control and modify electrical output with this cutting-edge introduction Pulse width modulation (PWM) is a method of modifying the amount of power delivered by an electrical supply by switching the electrical signal on and off at fixed intervals. The period between 'off' cycles--the pulse--can be adjusted to ensure that a given device is receiving no more power than it can use. PWM's applications in electrical engineering are innumerable, and its role in controlling output from sustaina... (Læs mere)
