Abstract

The Hexagonal power converter has become a suitable solution to provide high-quality voltage waveforms while achieving decoupled control of three DC terminals as well. In this case, the internal voltage balance of the different storage units is the main concern for the correct operation of the Hexagonal converter. Moreover, the Modular multilevel series- parallel converters (MMSPC) have become an interesting solution to provide higher operating voltages, reliability at a reduced cost, due to their ability to achieve a simpler internal voltage balance. In this paper, a Hexagonal power converter based on MMSPC for decoupled DC terminals is presented. The proposed system allows to implement a simple and cost-effective way to achieve a decoupled control strategy in each output of the system, to control the corresponding voltage of the system, along with maintaining the internal voltage balance of the proposed topology.
