Power Factor Correction in Power
Conversion Applications Using
the dsPIC® DSC
AN1106
This application note focuses primarily on the study, design and implementation of Power Factor Correction (PFC)
using a Digital Signal Controller (DSC).
Switch Mode Power Supply
(SMPS) Topologies (Part I)
AN1114
This application note explains the basics of different types of SMPS topologies and their applications. The pros
and cons of different SMPS topologies are also explained to guide the user to select an appropriate topology for a
given application, while providing useful information regarding selection of components for a given SMPS design.
Switch Mode Power Supply
(SMPS) Topologies (Part II)
AN1207
This application note is the second of a two-part series on Switch Mode Power Supply (SMPS) topologies. This series
expands on the previous material in Part I, and presents the basic tools needed to design a power converter.
