The modular double-cascade converter (MDC) is a new multilevel AC/AC converter topology, which has a modular structure. The proposed topology can be used in medium-voltage motor and generator drives, and in interfacing of grids of different voltages

Solid state transformers normally include a transformer whose operating frequency is well above the usual grid frequencies. These transformers are supplied by power electronic inverters such as an H-bridge. The average value of transformer supply vol

In power electronic converters soft switching is an efficient way to reduce losses. A resonant tank in series with the windings of the isolation transformer in a Modular Double-Cascade converter is presented. Positive effects such as switching loss r

A new multilevel converter topology with cascaded H-bridges and a multi-winding medium frequency isolation transformer is introduced. The proposed converter topology has a modular structure, which is achieved using cascaded H-bridges. The isolation f

In this paper voltage and frequency control of islanded microgrid after intentional and unintentional switching events are investigated. The weak low voltage (LV) network based microgrid consists of two inverter based distributed generation (DG) unit
