Control of doubly fed induction machine using a matrix converter

Abstract

This paper presents the control of a doubly fed induction machine (DFIM) via a matrix converter applied to the machine's rotor side. The experimental set-up shall be used to show its viability for wind energy applications. Stator Field Oriented control of the machine was implemented for active and reactive power control. The effects of harmonics, present in the rotor windings, on the control scheme were analysed. The paper also presents experimental results for power control and variable speed operation of the DFIM.
