| Abstract |
Traditional seven-level Active Neutral-point-clamped (ANPC-7L) converters suffer from the problems of dynamic voltage balancing in series switches and multi voltage levels jumping of phase output voltage during switching status transition. This paper presents a novel ANPC-7L topology with auxiliary commutating branches and elaborates on its commutating strategies. The presented topology and its commutating strategies resolve the two problems completely. The validity of the presented topology and its commutating strategies are verified by experimental results from a 380 V/5 kW ANPC-7L converter. |
