摘要
电力电子设备在各工业领域的广泛应用造成了日益严重的谐波污染问题,有源功率因数校正技术成为解决这一问题的有效方法。文章在分析传统Boost电路导致功率因数降低的原因和Boost APFC原理的基础上,针对目前功率因数校正效果偏低的问题,提出了双闭环融合电流前馈技术的控制策略,搭建了单相Boost APFC实验平台加以验证。实验结果表明,本控制方式具有功率因数高、输出电压稳定、动态响应效果好等优点。
The wide application of power electronic equipment in industry causes serious harmonic pollution. Active power factor correction （APFC） is an effective method to solve this problem. In this paper, based on analyzing the cause of lower power factor in traditional Boost circuit and principles of Boost APFC theory, aiming at the problem of low power factor in experiments, a control strategy of double closed loop fusion current feed-forward is proposed and a single phase Boost APFC experimental platform is built. The experiment result shows that this control method has the advantages of high power factor, stable output voltage, good dynamic response and so on.
