摘要
首先基于现有的、典型的模拟PFC控制芯片,较为详细地描述了单级升压变换的单相AC-DC变换器领域几种基本的有源功率因数校正技术,其中包括传统有源PFC技术、跟随有源PFC技术和单周期有源PFC技术。最后基于PFC控制芯片L4981B详细地介绍了支持较大功率输出的有源PFC电路设计过程,并给出部分实验结果。
Based on several current typical analogy PFC control ICs the firstly described detailedly are three single-phase active power factor correction techniques in field of single-phase AC-DC converters with single-stage boost conversion, including traditional PFC technique, voltage-follower PFC and one-cycle control （OCC） PFC. Next mentioned detailedly is a PFC design which supports high-power output by means of L4981 B, some experimental results are also given.
