AI-Enhanced EMC Digital Twin Automotive WBG Converters

Eligibility: UK/International (including EU) graduates with the required entry requirements

Duration: Full-Time – between three and three and a half years fixed term

Interview date: Will be confirmed to shortlisted candidates

The global shift toward electric mobility requires automotive power electronics with elevated power density, thermal performance, and efficiency. Adopting Wide-Bandgap (WBG) semiconductors, like Silicon Carbide (SiC) and Gallium Nitride (GaN), enables extreme switching frequencies and reduced losses. However, the fast switching transients produce severe high-frequency electromagnetic interference (EMI). Ensuring compliance with automotive standards (such as CISPR 25) traditionally requires extensive physical pre compliance testing late in the product cycle, resulting in costly iterations.

This PhD project addresses this bottleneck by developing a predictive, multi-domain Electromagnetic Compatibility (EMC) Digital Twin framework. The research combines electromagnetic modelling, machine learning, and hardware validation to deliver rapid virtual pre-compliance evaluation for automotive power converters.

This 3.5-year PhD studentship aims to develop an AI-driven Digital Twin capable of predicting high-frequency conducted and radiated emissions against CISPR standards, bridging 3D virtual simulations with real-world physical compliance testing.

The student will undertake a structured programme of virtual modelling, AI development, and experimental validation. Initial activity will involve designing baseline and degraded EMI layout prototypes for WBG converters and extracting layout parasitics using 3D electromagnetic solvers. Using these datasets, dual AI surrogates will be developed: a Gaussian Process Regression (GPR) model for low-frequency conducted emissions, and a Physics-Informed Neural Network (PINN) that embeds Maxwell’s equations to predict spatial radiated fields.

These surrogates will be integrated into a unified digital twin. Finally, the virtual framework will be validated and calibrated against prototype hardware.

Experimental diagnostics will utilise Coventry University’s pre-compliance laboratories to calibrate the AI models. By improving the reliability of virtual EMC screening, this project will help reduce the cost, risk, and time required to develop next-generation automotive power electronics.
