Title:
Phase-Shifted Full-Bridge (PSFB) Quarter Brick DC/DC Converter
Reference Design Using a dsPIC® DSC
Description:
This application note provides the digital implementation
of a telecom input 36 VDC-76 VDC to output 12 VDC,
200W Quarter Brick DC/DC Brick Converter using the
Phase-Shifted Full-Bridge (PSFB) topology. This topology
combines the advantages of Pulse-Width
Modulation (PWM) control and resonant conversion.
The dsPIC33F ?GS? family series of Digital Signal Controllers
(DSCs) was introduced by Microchip Technology
Inc., to digitally control Switched Mode Power
Converters. The dsPIC33F ?GS? family of devices consists
of an architecture that combines the dedicated
Digital Signal Processor (DSP) and a microcontroller.
These devices support all of the prominent power conversion
technologies that are used today in the power
supply industry.
