| Abstract |
The paper is concerned with new resonant converter configurations, belonging to the previously published dual channel dc-dc converter family. On one hand, the new configurations solve a significant shortcoming of the original ones, namely, the output midpoint potential was floating in comparison with the input midpoint. This caused a high-frequency oscillation of the output midpoint, often significantly limiting the application fields. Common ground can be used at the input and output sides at the new configurations. In addition, two of the new topologies also include electrical isolation, performed by an isolating highfrequency transformer. This property is often necessary in order to fulfill the strict industrial requirements against the power converters. |
