Multilevel power converters provide more than two levels of voltage to achieve smoother and less distorted ac to-dc, dc-to-ac, and dc-to-dc power conversion. This paper presents a generalized multilevel inverter (converter) topology with self voltage balancing. The generalized multilevel inverter topology provides a true multilevel structure that can balance each DC voltage level automatically without any assistance from other circuits, thus in principle providing a complete and true multilevel topology that embraces the existing multilevel inverters. From this generalized multilevel inverter topology, several new multilevel inverter structures can be derived. In addition, the generalized topology has led to some new multilevel structures such as P3D and P3C. In some applications such as capacitor-switched power conversion, voltage multiplier, and bi-directional dc/dc conversion, the generalized multilevel converter topology has a niche for implementing magnetic-less, compact, high-efficiency, zero-EMI, and low cost power conversion.
