A Parallel Connected Unfolding Bridge (PCUB) Multilevel Converter for HVDC Applications

Abstract: Hybrid Voltage Source Converters (VSC), that combine the conventional three-level VSCs and Modular Multilevel Chain-Links (CLs), offer a promising solution for future HVDC stations, achieving reduced footprint with respect to the MMC while maintaining high power quality and low loss. This paper introduces a new hybrid solution named 'Parallel Connected Unfolding Bridge Modular Multilevel Converter' (PCUB) which uses a parallel connection of phases on the DC side and comprises of wave shaping Chain-Links and un… Show more
