Abstract

This paper presents a comparative analysis of six digital current control techniques applied to three-phase voltage-fed PWM converters connected to the utility grid. Basic requirements are established and comparison criteria are used to justify the selected current control technique. The comparison contributes for the selection of the best current control technique for a given application. Finally, abacuses, tables and experimental results are shown in order to present the performance of these controllers under unbalances and harmonics in the grid voltages
