Gate Driver for Navy Power Electronic Systems
Abstract
We propose to develop a self-oscillating Ring Oscillator based PWM with a GaN interface to drive the gate of high voltage (1.7 kV) SiC switch. The switch ultimately will be either half-bridge or a full H-Bridge that is consistent with the development goals of theNavy iPEBB. We aim to develop a working prototype that can be integrated into the power electronic infrastructure of the new Navy programs for high-energy power electronics. Our high speed and self-regulating gate drive should be expandable from the initial 500kHz standard operation to several MHz potential future operation so that the profile of all the iPEBB building blocks can be more compact while maintaining the power density and reliability requirements.The expected consequences of this research program are primarily a new approach for control and application of high speed WBG semiconductor-based power converter and new design rules for appropriate solutions of exclusively WBG based gate drivers for converters and peripherals. We will develop approaches and tools to better describe the intricate static and dynamic parameters relationships in these systems as compared to other switch-mode converters. The expected results would certainly expand our understanding of near-MHz high power converters for Mega-Watt Naval systems and conceivably have practical uses by designers and users of switch-mode converters in general by creating in future a full system on a chip and similarly highly compacted Power Electronic Building Blocks (PEBB). Other expected significant outcomes are a unified mathematicaland network models of high frequency power converter systems that can help optimize the topologies and increase the efficiency. Theexpected contributions of this research in relation to dynamic modeling and control of power converter systems are in better control schemes for accurate tracking and fast stabilization and dynamic response.
