New Power Electronics and Electrical Machines Teaching Lab

We have recently commissioned a new Power Electronics and Electrical Machines teaching laboratory, within the School of Computing Electronics and Mathematics, Faculty of Engineering, Environment and Computing of Coventry University.

The new facility is going to enhance the existing Power Teaching lab with new, state-of-the-art test benches. It will indeed strengthen our ability to equip our students with the necessary skills, scientific and practical in the exciting area of Electrical and Electromechanical Power Conversion.

Summary:
This work presents a comprehensive and experimentally derived comparison of the static performance of commercial Gallium Nitride on Silicon (GaN-on-Si) devices and references their performance against a state-of-the- art Si Super-Junction (S-J) device. The Panasonic PGA26C09DV Enhancement mode (E-mode) p-GaN layer Gate Injected Transistor (GIT) and the Transphorm TPH320 series composite cascode GaN High Electron Mobility Transistor (HEMT) have been analysed and the experimental results illustrate typical performance characteristics of the different device technologies. Their experimental performance characteristics have been validated, explained through literature and application considerations have been stated.

Paper accepted in IOP Semiconductor Science and Technology

The following paper was accepted for publication in a special edition of IOP Semiconductor Science and Technology, special issue on Silicon Epitaxy and Silicon Heterostructures.

Abstract
The cubic form of SiC (β- or 3C-) compared to the hexagonal α-SiC polytypes, primarily 4H- and 6H-SiC, is of special interest because it has lower growth cost and can be grown heteroepitaxially in large area Silicon (Si) wafers. This in conjunction with the recently reported growth of improved quality 3C‐SiC, make the development of devices an imminent objective. However, the readiness of models that accurately predict the material characteristics, properties and performance is an imperative requirement for attaining the design and optimization of functional devices. The purpose of this study is to provide and validate a comprehensive set of models alongside with their parameters for bulk 3C-SiC. The validation process revealed that the proposed models are in a very good agreement to experimental data and confidence ranges were identified. This is the first piece of work achieving that for 3C-SiC. Considerably, it constitutes the necessary step for Finite Element Method (FEM) simulations and Technology Computer Aided Design (TCAD).
