Abstract This paper provides analysis of losses in the hysteresis-driven three-phase power converter with IGBTs and free-wheeling diodes. The converter under consideration is part of the self-excited induction generator (SEIG) vector control system. For the analysis, the SEIG vector control system is used in which the induction generator iron losses are taken into account. The power converter losses are determined by using a suitable loss estimation algorithm reported in literature. The chosen algorithm allows the power converter losses to be determined both by type (switching/conduction losses) and by converter component (IGBT/diode losses). The overall power converter losses are determined over wide ranges of rotor speed, dc-link voltage and load resistance, and subsequently used for offline correction of the overall control system’s losses (efficiency) obtained through control system simulations with an ideal power converter. The control system’s efficiency values obtained after the correction are compared with the measured values.

In this paper, firstly,the mathematical model of three-phase asynchronous motor based on vector control system is introduced. Then,the question of coupling of flux, torque and current regulator is analyzed. The comparative study of feedback decoupling, feed-forward decoupling and cross coupling are developed qualitatively and quantitatively. According to this, the deviation decoupling method is proposed to realize the complete decoupling of current regulator. The simulation and experimental results show that, combined with the deviation decoupling and vector control, the decoupling of torque and flux linkage can be implemented completely, while the voltage coupling of current regulator can be eliminated. The results show that the proposed control scheme is feasible and has a fast dynamic respond.
