SiC/GaN power semiconductor devices theoretical comparison and experimental evaluation (2016)
Presentation / Conference Contribution
Li, K., Evans, P., & Johnson, C. M. (2016). SiC/GaN power semiconductor devices theoretical comparison and experimental evaluation.

SiC and GaN power transistors conduction loss and switching losses are compared in this paper. In order to compare performance of the same power rating device, a theoretical analysis is given to compare SiC device conduction loss and switching losses...

Developing power semiconductor device model for virtual prototyping of power electronics systems (2016)
Presentation / Conference Contribution
Li, K., Evans, P., & Johnson, C. M. (2016). Developing power semiconductor device model for virtual prototyping of power electronics systems.

Virtual prototyping (VP) is very important for power electronics systems design. A virtual prototyping design tool based on different modelling technology and model order reduction is proposed in the paper. In order to combine circuit electromagnetic...

GaN-HEMT dynamic ON-state resistance characterisation and modelling (2016)
Presentation / Conference Contribution
Li, K., Evans, P., & Johnson, C. M. (2016). GaN-HEMT dynamic ON-state resistance characterisation and modelling.

GaN-HEMTs suffer from trapping effects which might increase device ON-state resistance (RDS(on)) values. Thus, dynamic RDS(on) of a commercial GaN-HEMT is characterized at different bias voltages in the paper by a proposed measurement circuit. Based...
