Abstract
Systems and methods for controlling a modular three-phase converter including two or more interleaved, parallel connected Voltage Source Converters (VSCs) utilizing a hybrid Space Vector Pulse Width Modulation (SVM) control scheme are provided. For the hybrid SVM control scheme, six active vectors utilized for SVM define six sectors in a space vector plane. Each sector is divided into two or more regions having corresponding optimal SVM switching sequences. In operation, a revolving reference voltage vector is sampled to provide a reference voltage vector. The SVM controller then identifies one of the regions in one of the sectors that corresponds to an angle and, in some embodiments, a magnitude of the revolving reference voltage vector and applies the corresponding optimal SVM switching sequence to the two or more interleaved, parallel connected VSCs.
