英语翻译
High-power synchronous motor drives are usually fed from naturally commutated cycloconverters.The output voltage of the cycloconverter contains interharmonics/subharmonics which affect the power quality and restrict the allowable frequency range.Further,a practical circulating current-free cycloconverter usually gives rise to stator current discontinuities.The present paper deals with a simulation method to study the performance of a cycloconverter-fed synchronous motor drive in the presence of interharmonics/subharmonics taking into account the discontinuities in the output current as well as the effect of ripple in the output current on the input current of the cycloconverter.Interharmonics in output phase voltage,output phase current,input supply current,and the field current are estimated and verified with experimental results on a laboratory prototype.The significant oscillating torque components due to these interharmonics are identified in a typical case.The simulation results are useful in power quality studies for such drives and in devising methods for suppression of these interharmonics/subharmonics.
