| Abstract: | The current topologies of single-stage PFC DC/DC converters with the direct power transfer (DPT) technology is analyzed, and the mechanism and implementation of the DPT technology are described. The result obtained the shows that applying DPT technology to the single-stage PFC AC/DC converters can not only effectively decrease their DC bus voltage, but also improve their conversion efficiency, so they are more promising in low power application. |
