Update on the development of a medium voltage multilevel cascaded H-bridge STATCOM

At AUPEC 2007 a paper was presented titled “Design and Development of an 11kv H-Bridge Multilevel STATCOM”. This paper is an update of this former paper, and will present some preliminary experimental results and practical insights gained into the control of a low voltage prototype system that has been completed and commissioned since the previous paper. Early results showing output waveforms from the low voltage prototype will be presented. Furthermore, lessons learned with respect to the hardware architecture and control algorithms will be highlighted.
