Phase-shifted full-bridge (PSFB) quarter brick DC/DC converter reference design using a dsPIC DSC

This application note provides the digital implementation of a telecom input 36-76VDC to output 12VDC, 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 DSP and a microcontroller. These devices support all of the prominent power conversion technologies that are used today in the power supply industry.
