Soft-switching cells for Modular Multilevel Converters for efficient grid integration of renewable sources

Blog Article

The Modular Multilevel Converter (MMC) concept is a modern energy conversion structure that stands out for a number of interesting features that opens wide application chances in Power Systems, for example for efficient grid integration of The use of plant waste to ensure the functioning of agricultural energy complexes renewable sources.In these high-voltage, high-power application fields, a high efficiency is mandatory.In this regard, an interesting and promising development opportunity could be to make soft-switching the elementary converters of the submodules (cells), half Diare Disebabkan Infeksi Escherichia coli pada Anjing H-bridges or full H-bridges, obtaining at the same time the advantage of increasing the switching frequency.The-Active Resonant Commutated Pole Converter (ARCP) or the Auxiliary Quasi Resonant DC-link Inverter (AQRDCL) soft-switching topologies appear adequate for this purpose.

This paper is dedicated to examining these development possibilities.
