Abstract
Voltage sags (or dips) are the most common power quality problem. The aim of this paper is to propose a multilevel-cascaded converter, connected in series with the supply, which acts as a sag compensator. The converter is direct-coupled and eliminates the use of costly output filters and injection transformers. The converter operation and control techniques are discussed and confirmed with simulations and practical results.
