| Abstract: | In this paper, characteristics of electrical specifications, which is peculiar for Brick-Configuration DC-DC power product, is analyzed in detail, selective requirement of topologies for this type of product is presented as well. The topologies listed as follows are the presented appropriate candidate ones for Brick DC-DC: Active-clamped forward converter, Resonant reset forward converter, Symmetrical half-bridge converter, Forward-flyback converter, Isolated boost-buck converter, Two-stage converter. The related techniques about the candidate topologies are respectively specified, furthermore in view of the applicability, both the advantage and the disadvantage are respectively compared with each other. Finally, good applicability of active-clamped forward converter to Brick DC-DC is further verified by the experimental result. |
