Abstract:
Electromechanical system with power converter is represented. The system includes three-phase induction motor. Each phase is made of two half-windings, which are installed in the same slot and connected via IGBT transistors to different voltage phases according to the certain rules. The system is supposed for enhancing rotating speed twice.
Mathematical model of this system is developed for PC. The model is supposed for evaluating how design affects dynamic and static characteristics of this system. There is a unit to analyze the power quality.
   
Key Words: mathematical model, induction motor, IGBT-transistors, frequency converter, half-windings
