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.

Offline UPS Reference Design

AN1279

The application note describes the design of an Offline Uninterruptible Power Supply (UPS) using a Switch Mode

Power Supply (SMPS) dsPIC Digital Signal Controller (DSC).

Digital Power Interleaved PFC

Reference Design

AN1278

The application note describes the design of an Digital Power Interleaved PFC (IPFC) using a Switch Mode Power

Supply (SMPS) dsPIC Digital Signal Controller (DSC).

Quarter Brick DC-DC

Reference Design

AN1335

This application note describes the design of Quarter Brick DC-DC Reference Design using Switch Mode Power

Supply (SMPS) dsPIC Digital Signal Controller (DSC)

DC-DC LLC Resonant Converter

Reference Design

AN1336

This application note describes the design of DC-DC LLC Resonant Converter Reference Design using Switch

Mode Power Supply (SMPS) dsPIC Digital Signal Controller (DSC)

Grid Connected

Solar Microinverter

AN1338

This application note describes the design of Grid Connected Solar Microinverter Reference Design using Switch

Mode Power Supply (SMPS) dsPIC Digital Signal Controller (DSC)
