摘要
以单相Cuk型变换器合成三相功率因数校正(PFC)电路为研究对象,鉴于目前三相PFC技术不是很成熟,设计中将三相交流电分成单相A-B,B-C,C-A分别进行PFC后加以功率合成。将升压型平均电流控制的PFC思想用于Cuk型电路拓扑,设计了一个具体、实用的具有有源功率因数校正(APFC)功能的有源功率因数校正器,分析了其主电路的工作过程,并计算了主电路的参数值,同时解决了常规单相Cuk型APFC电路直接并联存在的相间耦合问题,最后通过仿真和实验结果验证了理论研究的可行性。
Based on the three-phase power factor correction using single-phase APFC of Cuk converter as the research ob-ject,in view of the fact that the technology of three-phase power factor correction is not full-blown,this paper divides the three-phase alternating current into A-B,B-C,C-A single-phase alternating current to carry on the power factor correction.The idea of Boost average current control PFC is adopted in Cuk topology to design an idiographic and banausic circuit with active power factor correction（APFC）,then calculate the value of the components.The problem of the phase interac-tion among three-phase APFC circuit composed of normal single-phase APFC Cuk circuits in parallel is solved,the simu-lative and experimental results verified its validity.
