The purpose of this work is to study voltage control and energy balance of a split DC bus topology within a power electronics equipment connected to the AC mains, such as UPS systems, wind power generators, active filters and FACTS devices. A typical configuration in such equipment has two mains connected converters sharing a common DC bus, one series connected and the other parallel connected. The...
This paper describes various problems in transmission and distribution systems and demonstrates the significance of reactive power management. Static VAR compensator and STATCOM principles of operation and power characteristics are described. The most common types of multilevel voltage source converters used in STATCOM applications are comparatively analyzed. The most promising topology of multi-level...
