| Outline of Final Research Achievements |
Modular multilevel matrix converter (MMxC) for low frequency transmission that is applicable to off-shore wind farms is investigated. Its converter arm is composed of series-connected H bridge cells, and each H bridge cell consists of 4 switching devices and a capacitor. Thus the MMxC is able to output multilevel waveforms and therefore suitable for high power and high voltage applications. In this research, for the MMxC, power flow control and capacitor voltage balancing control among H bridge cells using voltage space vector modulation are proposed. A broad frequency range of the proposed controls from a low frequency to a commercial frequency are verified through numerical simulations and experiments using a 2-kVA MMxC.
