Commissioning of a laboratory model of modular converter in full Delta connection
Janovec, Jiří ; Kokeš, Petr ; Semerád, Radko
A laboratory model of MMC (Modular Multilevel Converter) was created and put into operation. The converter consists of series-connected FHB (Full H-bridge) cells and other necessary devices (for measurement, synchronization and pre-charging). The MMC was tested in topology of full Delta connection with 5 cells in each of 3 branches. The MMC was loaded for symmetrization of 1-phase 3.4kW resistive load (i.e. the branch current approached 5Amp rms). The power cells were completed with Slave units EPX and then controlled using TwinCat development system and EtherCat industrial data network. With the converter, control algorithms for symmetrization and compensation of 1-phase load for 3-phase power grid were tested.
