Abstract :
This The Permanent Magnet Synchronous Motors (PMSM) are used for medium power applications and preferred over conventional motors like Induction and Synchronous motors due its superior performance, efficiency and controllability. Normal voltage source inverters are suitable only for three phase drives. Cascaded multi-level inverters are used to improve the power quality. The Hexagram inverter has the advantages of both these inverters, while, it also drives six-phase motors which are more popularly used now. This paper deals with Hexagram inverter fed PMSM drive. Vector control scheme has been employed due to its benefits like better dynamic response. The PMSM has been modeled in dq frame and the drive system is simulated using MATLAB / Simulink. The results of the hexagram inverter and the drive structure are presented for various operating conditions. The model delivers promising results due to the multilevel property of the hexagram inverter and the vector control method.
