摘要
介绍了有源功率因数校正的工作原理及实现方法,并针对各种校正技术的特点进行了对比分析。之后着重分析了工作于连续调制模式下的升压型有源功率因数校正技术,并提供了完整的设计方案。实验表明应用该方案设计的功率因数校正电路可以稳定地将功率因数提高到0.99以上,并将总谐波失真降至10%以下。最后给出了实验的数据及部分波形。
A precision PFC/THD instrument for control of high performance boost active power factor correction (APFC) circuits operating at a fixed frequency in continuous conduction mode (CCM) is presented. After some words on a brief presentation and contrast of several APFC schemes, a detailed and mathematical analysis of the boost converter is proposed. The experimental result is a power factor of 0. 99 and total harmonics distortion (THD) of 10%. Finally, laboratory result and partial experimental waves are given as proofs.
