摘要
本文分析了开关器件、电感在硬开关Boost PFC电路中的损耗,并计算了Boost PFC变换器电路的开关损耗,给出功率损耗计算方法。通过对用有源功率因数校正集成电路UC3854实现的用于Sever Computer的600W开关电源的分析计算,用实验验证了Boost PFC电路功率损耗计算方法的正确性。
The power dissipations of switching components and inductor used in Boost PFC converter are analyzed, researched and computed, and then their distributions are figured out. Furthermore the paper rectified one 600W Switch Power Supply for server computer with UC3854 PFC controller, to prove the correction of the computer method.
