Analysis of Power Converter Losses in Vector Control System of a Self–Excited Induction Generator

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.
