Abstract
This paper represents structure of permanent magnet synchronous motor (PMSM) control system focused to work in field weakening mode. Structurally it consists of PMSM motor with open end winding, main bridge inverter (MB) with DC voltage at one side of motor winding and floating bridge (FB) inverter with a capacitor at the other side of motor winding. Structure of control system with active and reactive power distribution for MB and FB inverter with capacitor’s voltage level control and motor’s shaft control loops is proposed. Simulation model via Matlab/Simulink and Simscape language is designed. Comparing proposed control system with field oriented PMSM vector control and “Y” motor end winding connection is provided. Obtained results shows that proposed control system helps to reach 1.4 times more maximum speed that a conventional one
