Overview

CAUTION: This equipment operates at high voltages and currents which can result in hazardous electrical shock. Please make sure you understand and follow all necessary safety precautions prior to purchasing and operating.

TMDSHVRESLLCKIT is a DIMM100 controlCARD based motherboard evaluation module which uses Piccolo F28027 to digitally control a 300W resonant LLC half-bridge DC/DC converter with added synchronous rectification. The resonant LLC power topology is valued for its inherently high levels of efficiency credited to high frequency, low loss resonant switching. However, implementation of such a power converter can be challenging since the control theory is based in frequency modulation of the converter rather than the more typically seen duty cycle modulation. This solution guides users step-by-step through the complexities of a resonant LLC half-bridge converter, melding software and hardware design approaches to implement a complete high performance converter. The C2000™ Piccolo™ microcontroller is the digital controller for this design, enabling the resonant converter to operate at greater than 90% efficiency across wide load ranges, and with peak efficiency greater than 93%.
