Abstract
Increasing world electrical energy demand make necessary to develop new efficient and reliable schemes for power injection to the existing grid under distributed generation frames. In this work a novel DC-AC control scheme is proposed, which is based on one hand, on several 2L-VSI working together as a multi-modular converter in a parallel switching connection topology in the power converter stage and, in the other hand, a control strategy using two loops, an internal based on predictive voltage control and another external applying a PR current control, achieving THD levels lower than 1% for the injected current, accomplishing with the international standards for these kind of applications.
