STATCOM using the new concept of an inverter system with controlled gradational voltage.

This paper presents the STATCOM using the new concept of an inverter system which consists of three inverter units connected in series, and each inverter unit generates a different input voltage such as VC, 2VC, 4VC. This inverter system can output a high-quality voltage by a low-frequency switching operation. Thus, it can combine low loss and high quality. In this paper, we show the technique to apply STATCOM which uses the inverter system, and examination results. © 2009 Wiley Periodicals, Inc.
