PA – Modeling, Control and Performance Evaluation of Open-winding Permanent Magnet Synchronous Machine

The ever-increasing number of electric vehicles (EVs) is a remarkable ongoing change in the industry. Permanent Magnet Synchronous Machines (PMSMs) are currently the most widely used motors in EVs due to their high efficiency and power density. The stator windings of PMSMs in EVs are conventionally wye or delta connected. However, open-ended winding machines have some potential advantages, such as more design flexibility and control freedom.

Project Task: a) Literature review on the open-winding PMSM; b) Modelling a drive system (voltage source inverter + open-winding PMSM) with its control and modulation c) Performance evaluation of the drive system compared to wye-connected PMSM, e.g., losses/efficiency, safety under faults, etc.

Required prior knowledge: Fundamentals about power electronics, fundamentals of control, pulse width modulation.

Required software skill: MATLAB/Simulink or PLECS.
