Phase-Shifted Full Bridge DC/DC Power Converter Design …
Phase-Shifted full Bridge DC/DC Power Converter Design Guide Abstract The phase shifted full Bridge (PSFB) Converter is used for DC-DC conversion in various applications, for example in telecom systems to convert a high voltage bus to an intermediate distribution voltage, typically closer to 48V. PSFB stage provides voltage translation as well as isolation from the line voltage, since this topology includes a transformer. This document presents the implementation details of a digitally controlled PSFB system implemented on the HVPSFB kit from Texas Instruments. This kit converts a 400V DC input to a regulated 12V DC output and is rated for operations up to 600W.
Phase shifted full bridge (PSFB) DC-DC converters are used frequently to step down high DC bus voltages and/or provide isolation in medium to high power applications like server power supplies, telecom rectifiers, battery charging systems, and renewable energy systems. Traditionally, micro-controllers have
