Position: PhD Studentship in High-Performance Drive Inverter for ultra fast electric machines
Institution: University College London
Department: Department of Mechanical Engineering - Department of Mechanical Engineering
Location: London, United Kingdom
Duties: The aim of this PhD project is to develop, build, and test a highly efficient and compact integrated inverter drive for a high-speed compressor for fuel cell air supply. Development of a novel power electronic topology combined with utilising emerging high-bandgap power semiconductor devices (SiC and GaN), and novel thermal cooling technologies (microchannel cooling) can result in reduced inverter size, increased inverter efficiency, improved output current quality, and reduced motor losses
Requirements: Applicant should have, or expect to achieve, a master’s degree in engineering, computer science, or a closely-related discipline, awarded with first-class or upper second-class (2: 1) honours (or equivalent). The successful candidate should have strong self-motivation and dedicated passion for research, in addition to the willingness for team-working and the ability to deliver research outcomes to meet deadlines

In this regard, Fuel cells are growing in popularity throughout the E-mobility industry. Fuel cells require a constant supply of pressurized air, for which high-speed turbo-compressors with air bearings are an ideal choice for reducing size and ensuring oil-free operation for the lifetime of the container. However, the inverter driving the electric motor of the turbo compressor will not scale down with increasing speed, leading to a considerable. In addition, the existing solutions do not have satisfactory efficiency, reliability or power density. To address key challenges facing the drive inverter of a high-speed motor drive, a technological breakthrough on the drive inverter is necessary. The aim of this PhD project is to develop, build, and test a highly efficient and compact integrated inverter drive for a high-speed compressor for fuel cell air supply. Development of a novel power electronic topology combined with utilising emerging high-bandgap power semiconductor devices (SiC and GaN), and novel thermal cooling technologies (microchannel cooling) can result in reduced inverter size, increased inverter efficiency, improved output current quality, and reduced motor losses. Research Objectives The specific project objectives are: To create the topological model of a novel multilevel inverter to drive a high-speed electrical motor with specific specification, i.e., 20kW, 400V, 150kRPM. To design and build a highly optimised 20kW integrated inverter drive in order to experimentally evaluate its performance under all operating conditions. Full validation of the technology with its performance and economics proven and optimised. Exploitation of the project outcomes and technology translation through close collaboration with project partner, Control Techniques Dynamics, aiming to commercialise the technology. Studentship Description Successful candidates will join an interdisciplinary team with substantial industrial engagement and academic collaborations, as such they will be able to continue their career in this exciting field delivering future enabling technologies for the automotive industry. Person Specification Applicant should have, or expect to achieve, a masters degree in engineering, computer science, or a closely-related discipline, awarded with first-class or upper second-class (2:1) honours (or equivalent).
