| Popis: |
This paper presents a new low-loss modulation technique for the hybrid three-level four-leg converter. The total losses of the converter are reduced on about 18% in average compared to the standard three-leg neutral-point-clamped converter. Furthermore, the low-frequency voltage oscillation in the neutral-point is completely cancelled, and maximum benefit of the dc-link voltage is obtained. All these facts, together with the fault-tolerant ability due to the fourth leg, make this topology very interesting for applications such as wind generation, in which it is important to maximize efficiency and reliability. Some experimental results confirm good performance of the proposed modulation technique. |
