Influence of a dead time duration on the input current spectrum of voltage-source active rectifiers

Abstract

The paper discusses the influence of a dead time duration on the input current spectrum of voltage-source active rectifiers. The main body shows the simulations of a three-phase voltage-source active rectifier with respects to the dead times. This section especially describes the figures which present the harmonics analysis of the input current and its dependence on the dead time duration. The last part of the paper discusses the Total harmonic distortion of the current and effect of the dead times on this comprehensive indicator of the distortion. The higher dead time duration causes additional harmonics and it mainly affects odd harmonics.
