摘要
While several DC-DC converters for HVDC have been proposed in literature, comparison studies are needed to identify the best circuit for a particular case of application. This paper proposes an analytical methodology that allows to assess rapidly the comparison of DC-DC converters. It was applied to evaluate two modular DC-DC structures, one isolated circuit and one non isolated circuit, focusing in the variation of the operating frequency for different DC voltage transformation ratios. The results show that the non-isolated structure presents better indicators compared to the isolated circuit for all the considered cases.
