A power converter 100 includes a DC capacitor C, semiconductor switch groups each of which includes semiconductor switches connected in series to each other, bridge-cells llu-j, 11v-j, and 11w-j each of which includes the DC capacitor C and two semiconduct...

In relation to a three-phase power converter that is formed with three clusters, each of which includes one or a plurality of unit cells, a conventional three-phase power converter needs to be designed so that the DC capacitor included in the unit cell wit...

The method involves connecting an alternating-current (AC) path to an AC mains, and connecting an electrical memory circuit in series with the AC path. A capacitor of the memory circuit is associated with a switching device that is driven such that a charg...

The present invention relates to a delta connection cascade multilevel converter (CMC) where three single-phase converters are delta-connected, which eliminates the need for a large-capacity heavy single-phase reactor of the conventional delta connection C...

Proposed is a method for the determination of a control scheme for a neutral point clamped (NPC) voltage source converter (VSC) with at least 3 levels, in particular as a shunt active power filter, with a topology of three bridge legs (21-23) between each ...
