摘　　要：升压电感作为交错并联Boost PFC系统的关键元件,其寄生电容的损耗会对系统的效率产生影响。作者针对传统升压电感存在寄生电容大、损耗高的问题,提出了一种具有寄生电容小、损耗低等优点的改进设计方法,设计了一个685W的带交错并联Boost PFC的样机系统。测试结果表明:较之传统方法,作者所提改进方法搭建的系统具有更高的效率,更能适应交错并联Boost PFC的高效发展。The boost inductance is the key components of the interleaved Boost PFC system, and its parasitic capacitance loss will influence the system＇s efficiency. Due to the larger parasitic capacitance and the higher loss in traditional Boost inductance, this paper proposes an improved method which has the smaller parasitic capacitance and the lower loss, and designs a 685 W prototype system with an interleaved Boost PFC. Compared with the traditional method, the experimental results show that the system with the proposed improved method has a higher efficiency. Thus, this method is more suitable than the traditional one in the high efficient development of the interleaved Boost PFC.
