Control and Experimental Verification of Unidirectional 3-Phase AC/DC Power Converter Using Single-Delta Bridge-Cell Converter
The Single-Delta Bridge-Cell (SDBC) converter, a type of modular multilevel converter, features a circuit configuration that enables both compact design and high-power capacity, while offering excellent reactive power compensation capability for power grids.
In this study, a novel DC/three-phase power conversion system combining an SDBC converter with a single-phase diode rectifier is proposed. The proposed system enables not only reactive power compensation for grid stabilization but also active power supply to loads. Through this approach, the feasibility of a high-performance power converter capable of fulfilling multiple roles in future power systems is demonstrated.
This research is expected to contribute to the development of efficient and stable power conversion technologies for next-generation power grids.
