| Outline of Research at the Start |
The research is designed around 5 work-packages, covering a period of 3 years. Year 1 is mainly dedicated to developing a novel joint design framework, leading to prototyping and demonstration of each component in Year 2.
Year 3 is for system level demonstration and dissemination of results.
|
| Outline of Final Research Achievements |
The research produced a total of 10 papers submitted to specialist international conferences and journals. Highlights of research achievements include: prototyping of a high power-density motor; demonstration of high-frequency high-efficiency inverter with voltage boost capability and excellent harmonic signature; demonstration of split-mid-^point modular inverter design with load dependent variation of effective semiconductor area for reduction of losses; parametric machine-inverter co-design to optimise the energy efficiency of a motor drive over a driving cycle.
|
| Academic Significance and Societal Importance of the Research Achievements |
Electric motor drives make up for over 90% of all power electronics applications. They are pivotal elements of society infrastructure. Integrated design enables new development paradigms, improved performance, power density and reliability, which open the path towards new deployment opportunities.
