Abstract
A multilevel inverter topology clamped together by active and passive devices is proposed in this paper, which is based on the analysis of the existing three types of multilevel converter topologies. The new topology can balance DC link capacitor voltages by itself without additional circuit and separated DC voltage sources, regardless of load characteristics. It can be used in real power and reactive power conversion applications. The topology structure, operating principle and self-voltage balancing ability are analyzed. Finally, the validity is confirmed by simulations and experiments based on a five-level inverter.
