Abstract

In this work, the power quality standards such as IEC 61000-3-6, IEC 61000-2-12, has been satisfied for single-phase medium voltage applications. Eleven-level Cascaded H-Bridge (CHB) converter has been proposed which has been controlled using various level shifted modulation techniques. The ER G5/4 power quality standard has been met, which has the strictest grid codes at medium voltage level. In order to achieve this goal, symmetrical CHB with variable DC Links are employed, while the converter has a low number of switching transitions. The proposed topology has been implemented using four different modulation techniques. Also the performance analysis is done to evaluate THD of the system under various grid code conditions.
