The fisrst interests on the proposed technique is the series connected step inverter stages, which represents a mature solution as an alternative to the true series connection of a great number of modern turn-on and turn-off power semiconductor devices.multilevel convertertraction systemsIGBTDC/DC converterA Direct coupled 4-Quadrant Multilevel Converter for 16 2/3 Hz traction sytemstext::conference output::conference proceedings::conference paper
