This paper proposes a transformerless bipolar multistring dc–dc converter based on series-connected submodules. It is intended for converting dc voltage and managing power flow for medium-voltage high-power dc networks. This new converter has a flexible structure of multistrings and each string consists of four valves with their middle points crossly connected through two cost-effect dc capacitors...
This paper presents a new seven-level voltage source converter (VSC) for high-power medium-voltage (MV) motor drives. The proposed topology is composed of H-bridge connection of two nested neutral-point-clamped (NNPC) converters called 7L-HNNPC converter. This converter has interesting features such as operating over a wide-range of output voltages particularly for a range of (10kV-15kV) without the...
A new power converter interface for permanent magnet synchronous generator (PMSG) based wind energy conversion systems (WECS) is presented in this paper. The converter stage is capable to step-up the low-voltage side of standard six-phase PMSG used in today's WECS to a medium-voltage grid side. The proposed converter is an hybrid back-to-back topology composed of two series connected three-phase voltage...
