Comparison of the harmonic distortion of current source and voltage source inverters

Abstract

This paper indicates a basic approach to compare the harmonic impact of current source and voltage source inverters. The latter as a kind of status quo for distributed generation and the first as an uncommon topology in the area of self-commutated infeed. Therefore it is shown how to calculate the fundamental frequency power exchange – what we want. Also the differences in the frequency dependant damping of the inverters higher harmonic output shall be analysed – what we do not want.
