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.
A Switching DC power supply (also known as switch mode power supply) regulates the output voltage through a process called pulse width modulation (PWM). The PWM process generates some high frequency noise, but enables the switching power supplies to be built with very high power efficiency and small form factor.here are two main designs for the DC power supplies: Linear DC Power Supplies and Switching DC Power Supplies.
