Wind power is one of the most promising emerging renewable energy technologies for distributed generation (DG). In this paper, a new nine-level active neutral-point-clamped (9L ANPC) converter is proposed for the grid connection of large wind turbines (WTs) to improve the waveform quality of the converter output voltage and current. Therefore, the bulky passive grid filters can be reduced or even...
3L-NPC topology is usually used in MW wind turbine (WT) systems with full-scale converter configuration. However, due to its drawback of unequal device loss distribution, the converter rated power, and thus the WT unit capacity is limited. Moreover, in cased of device failure in generator converter, in order to protect the WT system, the converter has to shut down to disconnect the WT. This paper...
As a new multilevel converter topology, active NPC (ANPC) converter is very competitive for utility interface of large wind turbines. To meet the harmonics limit according to standards, such as IEEE, VEDW and IEC, passive grid filter is usually required, which is bulky, heavy, and may cause parasitic resonance in the mains. This paper proposes a new 9-level ANPC converter topology to achieve filterless...
