Introduction to Pulse Width Modulation. A look at a powerful technique for controlling analog circuits with a microprocessor's digital outputs. Pulse width modulation (PWM) is a powerful technique for controlling analog circuits with a microprocessor's digital outputs. PWM is employed in a wide variety of applications, ranging from measurement and communications to power control and conversion.
That's the basics of what a PWM is. Its a device a device that breaks up a DC voltage (like the 12 volts from our car's electrical system) into pulses which can be changed to our needs. When we change the width of the pulses, we are modulating them. Hence it should now be clear what Pulse Width Modulator means.
