A novel high-efficiency space vector modulation (SVM) strategy is proposed in this paper. It is based on the simultaneous and combined use of two strategies. The former consists of commutating only one switch of each inverter leg within each modulation period. In this way, there is no need to impose the dead time. The latter performs a step-by-step change of the modulation frequency in order to reduce the distortion of the inverter output voltage. The proposed system has been implemented and carried out on a programmable logic device (PLD) digital board. For validation, an experiment has been set up and several tests have been performed. The results have been compared with the ones achieved by means of the traditional SVM technique.

Abstract

A novel high-efficiency space vector modulation (SVM) strategy is proposed in this paper. It is based on the simultaneous and combined use of two strategies. The former consists of commutating only one switch of each inverter leg within each modulation period. In this way, there is no need to impose the dead time. The latter performs a step-by-step change of the modulation frequency in order to reduce the distortion of the inverter output voltage. The proposed system has been implemented and carried out on a programmable logic device (PLD) digital board. For validation, an experiment has been set up and several tests have been performed. The results have been compared with the ones achieved by means of the traditional SVM technique.
