【 摘 要 】

The economic growth in Asia is now remarkable. Because of this, the energy consumption has also increased drastically. Under such condition, it is necessary for efficient use of energy to introduce smart grid. At that time, electromagnetic interference (EMI) generated by the voltage harmonics from power converters which are connected to the power system becomes one of the biggest issues. Therefore, to suppress voltage harmonics in the power converters is required. Although it can be realized by connecting passive filters, it leads to circuit enlargement. On the other hand, recently there are some suggestions that the multilevel converters will be miniaturized and integrated in the future. If such a converter is introduced, it is considered that the smart grid system with renewable energy sources can provide high-quality electricity without EMI. Therefore, in this paper, the voltage harmonics to the grid system by assigning multi-level converters is investigated.
