| Abstract(in English) | In recent years, distributed power generation systems, such as photovoltaic power generation and fuel cells, have become increasingly popular from the viewpoint of decarbonization, and DC power feeding systems are attracting attention for their effective use of generated power. In order to introduce a DC power supply system, an AC/DC converter is indispensable to connect it to the existing AC grid. Therefore, the authors focused on transformers used in AC/DC converters. In conventional AC/DC converters, power quality can be improved by using multiphase transformers. However, when a transformer is multiphased using the conventional method, the number of phases on the secondary side of the transformer is increased by combining phase windings such as staggered connections, which leads to the disadvantage of a larger transformer due to the increase in secondary side windings and higher costs due to the increase in windings. Therefore, the authors have proposed a transformer with a special winding structure that can minimize the increase in secondary-side windings by using a special winding structure. In this paper, the authors calculated and compared the losses of an AC/DC converter with a multiphase transformer with a special winding structure and with a multiphase transformer with a conventional connection method. As a result, it was found that the loss increased when the special winding structure was used in a 6-phase transformer compared to the conventional 6-phase Δ-YΔ transformer, but the loss could be slightly reduced by using the special winding structure in a 12-phase transformer compared to the conventional method. |
