| Popis: | This paper describes different variants of realization of new traction drive for AC- power system based on medium frequency transformer MFT. These topologies enable to minimize weight of traction transformer. Basic variants of input high voltage converter realization (using modular multilevel converter MMLC, indirect frequency converter with VSI, matrix converter or other direct frequency converter) have been compared. For these basic variants the modifications are solved (with different power circuits and with different control algorithms). Special attention is given to single-phase high voltage matrix converter with input filter used serial connection of capacitances (realized in laboratory). |
