Description
This application note focuses primarily on the study, design and implementation of Power Factor Correction (PFC)
using a Digital Signal Controller (DSC).
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.
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.
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).
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).
This application note describes the design of Quarter Brick DC-DC Reference Design using Switch Mode Power
Supply (SMPS) dsPIC Digital Signal Controller(DSC)
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)
This application note describes the design of Grid Connected Solar Microinverter Reference Design using Switch
Mode Power Supply (SMPS) dsPIC Digital Signal Controller(DSC)
This application note presents a fully digital-controlled 720W AC-to-DC (AC/DC) power supply, which meets all CSCI
Platinum Specifications, as well as providing a variety of additional, application-specific features and functions.
