This paper presents a single-phase seven-level stack multicell converter (SMC) which provides a viable solution for multilevel converter. Conventional cascaded multilevel inverter (MLI) removes the drawbacks of clamping diodes and clamping capacitors topologies. However, in a cascaded MLI number of voltage source and power switches increases as the number of level increases. The main advantage of...
This paper proposes a novel inductive contactless energy transfer system for residential distribution networks. The system is based on a resonant inverter with sliding transformers, allowing high flexibility (the connection point of the loads is movable) and high safety (electrical shocks are avoided). A new resonant topology for driving the sliding transformers is proposed which behaves as an AC...
An advanced composite five-level converter is proposed in this paper, which owns the clear advantages of power devices reuse and composited clamping. The proposed five-level converter is derived by integrating dual three-level T type modules and one three-level neutral point clamped (3L-NPC) module. Due to the power device reuse scheme, the proposed five-level topology can be also taken as composition...
To decrease the number of clamping diodes and flying capacitors in multilevel inverters, a novel multilevel inverter topology with no clamping diodes and flying capacitors is proposed in the paper. The topology structure, operating principle, balance of the DC link capacitor voltages, and comparisons with the conventional multilevel topologies will be discussed. The number of power switching devices...
