Pulse Width Modulation for Control and Automation

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 susta...
