Optimisation of WBG power converters and gate drivers to reduce EMI  

Power converters can gain significant performance improvements when using Wide Band Gap semiconductor switches mainly due to the improved switching speeds of these devices. This however, typically, causes significant challenges with regards to Electro Magnetic Interference. Radiated Emissions and Conducted emissions can pose significant challenges in particular to the power converter designer mainly due to this inherent increase in switching speed. Therefore, several aspects of the power converter will be investigated to maximise the advantages of these Wide Band Gap semi-conductors while still achieving good EMI performance. 

Aspects covered in this project can include, type of wide bandgap switch, power converter topology, gate drivers, physical layout and output/input filtering among other topics.
