Phase-Shifted Full Bridge DC/DC Power Converter Reference Design


This design is a digitally-controlled: phase-shifted full bridge 600W DC/DC converter. A C2000™ Piccolo™ microcontroller is the controller for the phase-shifted full bridge converter: supporting peak current mode control and synchronous rectification. The Piccolo microcontroller implements high performance peak current mode control without any external support circuity: a distinctive capability amongst microcontroller-based designs. This design is able to achieve high efficiency across wide load ranges with peak efficiency greater than 95%: while supporting ZVS switching across the entire load range. Further: getting started with this design is easy. A GUI is provided as a convenient way to initially evaluate the functionality of the design and the Piccolo microcontroller. When ready to explore further: step-by-step documentation details the implementation of the underlying software and hardware.

  • Full microcontoller-based control of phase shifted full bridge DC/DC power conversion 400V DC input: 12V DC output: 50A rated output (600W) Peak current mode control microcontroller implementation without need for external circuitry Synchronous recitification support for increased power efficiency Adaptive zero voltage switching (ZVS) across entire load range Fault protection including input under voltage: input over voltage: over current: and output under voltage NOTE: Software for this board can be found inside the controlSUITE™ software package.
