Preface
The main purpose of a switch mode power supply is to convert the AC power into a stable DC power applied to a variety of electronic products. Switching mode power supplies, based on their function, can be divided into AC/DC (AC to DC power supplies) type and DC/DC (DC to DC power supplies) type.

SMPSs are widely used in computers, office automation equipment, industrial control equipment and communications equipment. The trend of SMPS will go toward smaller, lighter and more efficient power supplies.

This document will introduce how an oscilloscope can be used for power analysis of SMPS, such as ripple, power quality and harmonics.
