We offer 4-year PhD position in Topology Morphing Control of Power Electronic Converters.
Supervisors: Research Professor Dmitri Vinnikov and Dr. Andrii Chub
Power electronics is a mature field with numerous solutions for typical applications. Nowadays, rapid electrification of industry, transportation, utility energy storages, households, etc. transforms power electronic systems into critical technology. Numerous applications had emerged. They require individual solutions due to limitations of conventional power electronic systems. Lack of universalization and concerns regarding reliability in power electronics impose challenges in life cycle cost optimization of these systems, electronic waste recycling, reusability and retrofitting, etc.
This project aims to unleash the design flexibility of power converters and adaptability of their control. It will result in the new class of power electronic converters with unique control enabling smooth on-the-fly reconfiguration of the converter topology to achieve balanced performance in a wide input voltage range and beneficially constrained voltage/current stress in its components. These features will widen application range of the new converters and significantly improve their reliability resulting from optimized performance among different control modes. Additionally, active thermal control will be employed to achieve unparalleled performance among wide input voltage range converters. Ph.D. student will work on the synthesis of novel dc-dc converter topologies capable of topology morphing control and their experimental implementation.
- Synthesis of galvanically isolated dc-dc converter topologies capable of topology morphing control
- Development of multimode control with smooth transition between modes for synthesized topologies
- Benchmarking of voltage and current stress in components in different modes of the developed topologies and estimation of accumulated damage
- Development of low-cost active thermal control methods and estimation of resulting lifetime extension
- Experimental verification of developed converters and control methods for selected applications
