The MMC converter is the key topology for HVDC applications. In these systems, a major complexity is the number of modules and components required per phase to achieve nominal voltage and current levels for applications in transmission system. In this paper, the topology and control of a two-phase MMC system for HVDC applications is presented. The main idea is to eliminate a complete phase of the classic MMC converter for reduce the number of modules and the complexity of the system, together with the use of MMSPC-type modules, in order to achieve internal voltage balance without the need of extra sensors and control loops.@en
