A new generalized fault tolerant space vector modulator for cascaded multilevel converters is presented. Exploiting the redundancy properties inherent in multilevel modulation schemes, a generalized space vector modulation algorithm is devised, also aimed to the extension of the normal, full rated operation, to a limited rate, fault tolerant mode. Based on the exploitation of switching vectors redundancy properties and discontinuous modulation technique, solutions have been devised for the equalization of semiconductor components switching frequency, in either no-fault and fault operating conditions, in order to reach an equal distribution of converter dissipated power.

Abstract

A new generalized fault tolerant space vector modulator for cascaded multilevel converters is presented. Exploiting the redundancy properties inherent in multilevel modulation schemes, a generalized space vector modulation algorithm is devised, also aimed to the extension of the normal, full rated operation, to a limited rate, fault tolerant mode. Based on the exploitation of switching vectors redundancy properties and discontinuous modulation technique, solutions have been devised for the equalization of semiconductor components switching frequency, in either no-fault and fault operating conditions, in order to reach an equal distribution of converter dissipated power. The new fault tolerant space vector modulation technique is validated through a case study.
