Generalized multi-cell voltage sourced converter

This paper introduces the generalized multi-cell converter topology. Its modular construction allows it to be scalable to different voltage and power levels. Several variations of this converter are introduced in this paper. Proposed converter offers a multi-input structure allowing it to integrate power from an AC network, a DC network, and/or a multitude of lower voltage distributed sources. Main applications of this topology include DC distributed generation and HVDC taps. Other applications are hybrid vehicles and high-power UPS systems. The converter is developed starting from the well-known cascaded H-bridge topology. A simulation case study is presented to demonstrate feasibility of the concept.
