—The analysis of a multicell topology that is implemented with single-phase nonregenerative cells under an unbalanced ac mains is presented. The study shows that the topology naturally compensates most of the voltage unbalance; for instance, for a 100% voltage unbalance in the ac mains, just 32% reaches the load. For critical applications, a feedforward(More)
—This paper presents a three-phase unified power-quality conditioner based on current source converters (CSC-UPQC), including the design guidelines of the key components , an appropriate control scheme, and a selection procedure of the dc current level. Particularly, the ridethrough capability criterion is used to define a minimum dc current level so that(More)
—Interharmonics exist in the ac supply currents in ac/dc/ac drives mainly due to the poor decoupled behavior of the dc-link stage. This issue is particularly evident when different input/output operating frequencies are used, causing harmful effects on power transformers and reducing the system efficiency and power quality. Consequently, large(More)
