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.
