摘　　要：提高开关电源的功率因数,既能提高开关电源效率,又能减小对电网的谐波污染。本文中绍一种基于单周期控制(One-Cycle Control,简称OCC)的新型IR1150芯片构成的有源功率因数校正器。给出Boost型APFC系统的主电路结构。分析和讨论了OCC技术原理以及有源功率因数校正器工作过程和系统的硬件电路结构,并设计制作了400W实验样机。实验结果表明,该校正器在宽输入电压范围(90～260V)下能够正常工作,功率因数达到0.99。It is urgent for increasing the power factor of switching mode power supply to improve the efficiency and reduce the grid pollution.A new Active Power Factor Correction （APFC） technique based on one-cycle control （OCC） is analyzed and then a Boost circuit is designed on the basis of IR1150 IC.The principle of APFC and the hardware structure are discussed in this paper.A 400W experimental circuit is built and the experimental results showed that the active power factor corrector can work well with the power factor of 0.99 in the wide input voltage range of AC 90～260V.
