Abstract :
The functionality of efficient synchronous rectifier components, specially developed for resonant DC-DC converter topologies designed to operate at high frequency, has been demonstrated in a series-parallel converter circuit operating at 420 kHz and 85 W. Conduction losses for these components are three times lower than for Schottky diodes. Switching conditions for efficient operation have been identified both experimentally and using accurate multilevel modeling
