Fourier Harmonic Analysis of Voltage Vectors in Four-Switch Space-Vector Modulated VSI

Jiří Klíma

Abstract

The paper presents closed-form expressions for the harmonic components of the space-vector modulated waveforms for four-switch VSI.. The analysis is based on space-vector decomposition technique for finding the symmetrical vector sequences. From the Laplace transform of the symmetrical voltage vectors we can derive relations for the harmonic spectrum. The harmonic spectrum are compared and verified with the measured results. As shown, there is an excellent agreement between the analytically calculated waveforms and the experimentally
