Coventry University is inviting applications from suitably-qualified graduates for a fully-funded PhD studentship. This is an exciting opportunity in cutting-edage research of power electronics electromagnetic compatability using fast switching power semiconductor devices. The project is in close collaboration with industrial partner FEV.

About the project

With an estimated over 50% energy efficiency improvement than traditional silicon (Si) devices, wide band-gap power semiconductor devices based on silicon carbide (SiC) and gallium nitride (GaN) are drawing increasing research interest in automotive applications to improve power density and efficiency, which finally impact on overall EV performance to increase autonomy range and reduce cost.

However, one side effect of wide band-gap devices in automotive applications is electromagnetic interference (EMI), which is due to devices fast switching. In order to propose new approaches to mitigate power electronics systems EMI level and to maximise its power density, it is necessary to understand noise source (device switching transitions) and noise propagation path at first. For this reason, it is important to use modelling technique to analyse power electronics systems EMI level. Based on accurate modelling results, effectiveness of different approaches for electromagnetic compatibility (EMC) can be studied, which will then finally be validated by experimental measurement for automotive applications.

The PhD project will be based at the Coventry University Centre for Advanced Low-carbon Propulsion System (C-ALPS) with close industry support from FEV. FEV are a global automotive engineering consultancy with over 4000 engineers and researchers worldwide (see 


Fully-funded project with industrial collaborator This includes fees covered UK/EU and monthly tax-free stipend as well as consumables and travel/conferences budget.


The successful candidate will receive comprehensive research training including technical, personal and professional skills.

All researchers at Coventry University (from PhD to Professor) are part of the Doctoral College and Centre for Research Capability and Development, which provides support with high-quality training and career development activities. 

The successful candidate will also have an exciting opportunity to acquire power electronics skills in both software and hardware operation and to acquire research and development experience in both research institute and industry.
