Abstract: Abstrmt-A technical and economic feasibility study of HVDC systems without converter transformers is presented. The presentation includes proposed solutions to the drawbacks related to the absence of galvanic separation between the ac and dc systems, if the converter transformers are eliminated. The results show that HVDC systems without converter transformers are both technically and economically feasible. The cost savings can be substantial.
