| Abstract |
This paper compares the performance of a five-level neutral-point clamped (NPC) converter and a fivelevel active neutral-point clamped converter (ANPC) for a medium voltage and variable speed pumpedstorage hydropower application. It is found that the ANPC converter has a lower current total harmonic distortion (THD) compared with the NPC converter under the same switching frequency, while the losses are higher. However, the simple structure and the easiness of controlling the DC-link voltage means that the five-level ANPC converter has a high potential in the market of the aforementioned application. |
