Summary
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). This reference design demonstrates how digital-
power techniques when applied to UPS applications enable
easy modifications through software, the use of smaller
magnetics, intelligent battery charging, higher efficiency,
compact designs, reduction in audible and electrical noise
via a purer sine-wave output, USB communication and
low-cost overall bill of materials.

Summary
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
reference design provides an easy method to evaluate
the performance and features of SMPS dsPIC DSCs for
an Interleaved Power Factor Correction application. The
Interleaved PFC reference design unit works with universal
input voltage range, and produces a single high voltage DC
output up to 350W of power.
