Abstract
This paper presents an effect of dead times on values of an input current harmonics drawn from an electric grid by a voltage-source active rectifier. The first part shows a derivation of the effect on one pulse of the voltage and then the values of the current harmonics are derived. The main section discusses a description of voltage with the pulse width modulation with respect to the dead time. A voltage waveform at the input terminals of the inverter, its harmonic analysis, and calculations of the current harmonics values are derived. The last part shows simulations and comparison of the harmonic analysis of the current with and without dead times.
