Control strategy of dual fed open-end winding PMSM drive with floating bridge capacitor

This paper proposes a control strategy of open winding permanent magnet synchronous motor (OW PMSM) in field weakening modes. There are two inverters. One of them connected to the traction battery. | Control strategy of dual fed open-end winding PMSM drive with floating bridge capacitor International Journal of Mechanical Engineering and Technology IJMET Volume 10 Issue 03 March 2019 pp. 1475 1482 Article ID IJMET_10_03_149 Available online at http www.iaeme.com ijmet issues.asp JType IJMET amp VType 10 amp IType 3 ISSN Print 0976-6340 and ISSN Online 0976-6359 IAEME Publication Scopus Indexed CONTROL STRATEGY OF DUAL FED OPEN- END WINDING PMSM DRIVE WITH FLOATING BRIDGE CAPACITOR A.S.

Shklyarskiy Chair of General Electrotechnic Saint-Petersburg Mining University St. Petersburg Russia ABSTRACT This paper proposes a control strategy of open winding permanent magnet synchronous motor OW PMSM in field weakening modes. There are two inverters. One of them connected to the traction battery. Main bridge inverter aimed to provide power with approximately unity power factor another one to capacitor. Floating bridge inverter aimed to control capacitor voltage on desired value and provide reactive power to the moto. Compare OW PMSM control system with conventional field-oriented control FOC shows that proposed method helps to reach speed 1.41 times more than FOC system. FOC system was simulated with 310V DC power supply. OW PMSM with 160V DC power supply and 500 nanofarad capacitor.

INTRODUCTION PMSM motor is widely used in traction applications because of its best mass dimensional ratio parameters high efficiency 1 2 . However one of the main PMSM motors problem is rapid torque decreasing while working in high-speed area. In 3-5 paper special
