| Outline of Final Research Achievements |
In this research, I investigated a novel circuit and control method of Hexagonal modular multi-level converter (H-MMC) for 3-phase AC/AC converter. I performed theoretical analysis for H-MMC and proposed new control methods with power flow management, capacitor voltage control and energy storage system.
I verified effectiveness of the proposed method by simulation(PSIM software). In addition, I developed an experimental system and control programs for H-MMC. I clarified that the proposed H-MMC system is able to operate stably and properly in steady state and transient by the experiment.
