In modern power system, the switching devices are generally used in combination with unbalanced reactive loads which produces current related Power Quality (PQ) problems by making source currents distorted and unbalanced. Usually a STATCOM is installed to support electricity networks that have a poor power factor and often poor voltage regulation. A Distribution Static Compensator (DSTATCOM) op...

Abstract: Three-phase two-level voltage source converters are used for distribution static compensator (DSTATCOM) applications and can be replaced by a multilevel inverter.
