Abstract

The Modular Multilevel Series Parallel Converter (MMSPC) not only allows dynamic interconnection among the modules in series connection, like the traditional Modular Multilevel Converter (MMC), but also in parallel connection. This extra switching state among the modules allows new features and operation modes. The parallel connection between modules enabled by the MMSPC, is not only limited to those modules belonging to the same arm, but can also be extended to the parallel connection of modules from different arms or even from different phases. All these different interconnections brings operational benefits as well as some constraints. In this paper, the power topology, operation and comparison of different MMSPC configurations are presented. Specifically, this paper describes in detail the traditional MMC (without parallel interconnection), the MMSPC with parallel connection of modules of the same arm only, the MMSPC with the option of paralleling connection among the phases of the system, the MMSPC with parallel connection between arms of the same phase and finally, the MMSPC with full-parallel capability.
