Brushless Doubly-Fed Reluctance Machine (BDFRM) Drivetrain
his project aims to design a cost-effective BDFRM drivetrain controlled by a matrix converter, eliminating permanent magnets and brushes to reduce material cost and maintenance. A reluctance-graph model supports accurate torque and flux estimation for predictive control over a wide speed range. High-voltage GaN devices are evaluated for efficiency and switching performance, delivering strong torque density and low inertia appropriate for utility vehicles and compact electric cars.
