An assessment of resonant gate drive techniques for use in modern low power dc-dc converters

This paper is concerned with the investigation of existing gate drive topologies for use in low power, high frequency, dc-dc conversion. Each topology's theoretical characteristics are examined and verified in a detailed mathematical analysis suite. Simulation and experimental results emphasize the advantages, or otherwise, of the selected topologies. Practical issues in developing high frequency resonant gate drives are explored. The optimum topology for low power, high frequency dc-dc converter applications, based on the findings of this work, is then identified.
