| Abstract |
Modular Multilevel Converter (MMC) topology is an interesting solution for number of medium andhigh voltage applications. Key advantages over another multilevel topologies include flexibility ofscaling in voltage and simple implementation of redundancy. In this publication control of DC-DCMMC is discussed. Analyzed converter consists of six branches connected in double wye structure.It enables bidirectional power transfer and step-up or step-down voltage conversion. The scope ofthe paper is branch energy balancing of the converter. Balancing system is derived from the analysis ofbranch powers during steady state operation. Operation of the control system is verified in the hardwarein-the-loop (HIL) simulator provided by OPAL-RT Technologies. Complete control loop realized onhierarchical system was implemented. The system is composed with a top-level controller (based onABB AC 800PEC) and a number of cell controllers build with Texas Instruments DSP (C2000 F28035). |
