Novel digital continuous control of SVM inverters in the overmodulation range

A novel technique for space vector modulation (SVM) inverters in the overmodulation range is presented. A unique algorithm manages the transition from the onset of overmodulation to six-step operation. The technique is suitable for a very simple digital implementation; experimental results, obtained by a DSP board, are also included in the paper.
