Active Neutral Point Clamped (ANPC) topology is an optimization of NPC converter and is very attractive in medium-voltage applications. In this paper, a new solution able to detect any type of power semiconductor switch fault inside the ANPC converter is proposed. This strategy allows to achieve fault tolerance of ANPC converter without...

Neutral Point Clamped (NPC) converter topology is one of the most widespread static conversion structures used in high power medium voltage industrial applications. In recent years, fault tolerance has become one of the most interesting features which could be requested by the market, in order to improve plants reliability and availability,...

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...

Two new fault tolerant multilevel PWM techniques, devoted to the command of Cascaded Multilevel (CM) converters, are presented: a Sine PWM with interleaved carriers technique and a Space Vector PWM technique, based on the redundancy properties inherent in multilevel modulation schemes. A performance comparison among the new devised PWM...
