Abstract

This article presents an approach for analysis and design of MOSFET gate driver circuits for Phase-Shifted Zero- Voltage-Switching Full-Bridge (PS-ZVS-FB) DC-DC converters. Based on the critical requirements of the converter, the performance indices of an effective driver stage are identified. A brief overview of MOSFET driving basics is extended to a comparative analysis of several commonly used gate driver schemes. Design guidelines of a high-performance driver stage using off-the-shelf IC technology are presented. Tests were carried out on a setup consisting of IRFP2907 MOSFETs driven at 200 kHz and performance features based on the test results are highlighted. Finally, the possible limitations and indications for further improvement are discussed.
