Abstract

Large drives fed by Cycloconverters (CCVs) are extensively applied in industrial and traction drives. For 12-pulse configurations, multi-winding transformers are employed. For high-power applications, three separated three-phase transformers with two secondary windings with star- and delta connection are used. In this paper, a study and evaluation of the interharmonics currents behavior injected by CCV in the transformer windings is presented. Field measurements and simulations support the analysis. Results supports further improvements concerning design, engineering and operation issues.
