Abstract

This paper presents the performance evaluation under grid voltage sags of a two parallel-interleaved grid-connected converters employing low switching frequency. A current controller based on the synchronous reference frame including voltage feed-forward is used. The dominant frequency components from the direct- and quadrature-axis voltage Vd and Vq are eliminated by using an adaptive moving average filter. The dynamic performance of the converter during voltage sags is improved using an adaptive approach which minimizes the filter delay during the faults. The presented results conclude the performance of the converter system.
