Afficher le Résumé
The operation and performance o f t h e thyristor/diode controller with passive loads are studied in detail. The voltage applied to the load is controlled by the chopping action of the thyristors and the resulting voltage and current waveforms are analysed. by means of Fourier analysis. to determine their harmonic content. The steady-state analysis o f athree-phase induction motor with thyristor/diode controller i s presented. A mathematical model suitable for the analysis is developed. State space modelling is employed and the initial vector pertaining to steady-state i s obtained directly. The steady-state solution for constant speed is obtained in a closed form in terms of state transition matrices with the motor represented in stationary d-q axes. Results of experimental studies on the motor under steady-state are presented. A good correlation exists between the experimental and theoretical results.
