Multilevel converters, which are supplied by cascaded capacitors and non-isolated DC sources, can not operate without capacitor voltage balancing. This paper proposes a capacitor voltage balancing technique for the dual three-level T-type advanced converter topology. The reason behind the capacitor voltage unbalance, of this topology, is discussed and clarified by using the converter power circuit...
Several power converter topologies have been presented for Inductive Power Transfer (IPT) systems to generate high frequency current to cite the primary side inductive coils/tracks. This paper proposed the neutral point clamped (NPC) and flying capacitor (FC) multilevel converters based IPT systems which are suitable for high power IPT applications. The modulation strategies for single phase as well...
Modular multilevel converter (MMC) is a newly introduced topology of multilevel converter with six arms, each of which is formed by a series connection of several chopper-cells and an inductor. This paper first analyzes the topology and working principle of high-voltage large-capacity MMC. Then, a novel control strategy and its system solution are proposed and explained in details, including staircase...
