Abstract
Due to the large number of components in the cascaded multilevel inverters, the probability of failure in one of the inverter's component is high and proportional to the inverter's level. In this paper is presented a fast space-vector algorithm with the purpose to avoid this issue. The presented algorithm is based in the reduction of the reference vector length and in the use of redundant states to produce balanced line output voltages when the converter is operating under a faulty condition. When compared with a well-known strategy from the literature, the results show its effectiveness and better performance.
