摘　　要：本文对现有的应用直接功率转换(DPT)技术的单级PFC AC-DC变换器进行了深入的分析和综合,阐明了它们的直接功率转换的机理和实现方法。分析表明,应用DPT技术不仅可以有效地降低单级PFC AC-DC变换器的直流母线电压,也较大地提高了效率,使其在小功率的应用中具有更大的前景。This paper analyzes and synthesizes the current topologies of single-stage PFC DC/DC converters with the direct power transfer (DPT) technology,and describes mechanism and implementation of the DPT technology. The result obtained 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.
