| Abstract |
The waveforms of a rectifier connected with mains are determined by the first harmonic, however, within a synchronous machines harmonics are generated due to asymmetrical load of the stator during rectifier operation. To investigate the influence of an asymmetrical rotor on system behaviour a damperless syncbronous machine with cylindrical rotor is considered. An accurate model is presented by calculating the analytical solutions of commutation and conducting period overlap angle is determined by iteration. Analytical solution allows to analyse the influence of system parameters on current harmonics. The model including machine harmonics leads to calculated waveforms which agree with measurements. Considerable overlap angles strongly influenced by load parameters and firing angles limit operation ranges of the rectifier. Rectified voltage is load dependent. Analysis of current waveform shows that harmonics dominate commutation. |
