Abstract :
Multilevel converters are very popular for high power AC drives to meet the power demands for large electric/hybrid electric vehicles. Emitter Turn-off (ETO) thyristor is one of the present state-of-the-art high power semiconductor devices. The newest version of ETO (Gen-4 ETO) is more intelligent and reliable. Packed with advanced features as well as superior performance, ETO device and ETO-based power converters are very attractive for large electric drives. This paper presents the ETO light neutral-point-clamped (NPC) converter design and thermal analysis. The modular digital controller architecture for this converter is proposed in order to improve the system reliability and increase its expansion flexibility. As a solution to further increase the converter output power, the ETO light active NPC (ANPC) converter is presented, and moreover its fault tolerant capability is discussed.
