Abstract

A step-up transformer is frequently used in frequency converter motor drives to increase the output voltage of the supply system to the rated value of the motor. In addition, a larger current requirement is satisfied with parallel frequency converters coupled via three-phase multi-primary step-up transformer. The electrical harmonics have effects on the assembly losses and the drive performance, which is why the harmonic content of the frequency converter drives including magnetic components is an important issue to be taken into consideration. In this paper, the harmonic content of the introduced specially designed frequency converter drive is measured and further analyzed
