单相Boost有源功率因数校正电路的研究
资料介绍
基于平均电流模式控制技术,设计并制作了一台1kW单相Boost有源功率因数校正装置。功率因数校正系统设计采用双闭环控制方法,电流内环实现样机输入电流跟踪输入电压按正弦规律变化,电压外环维持输出电压不变。实验结果表明,实验样机可获得高功率因数,电流畸变小,并且样机动态响应速度快、抗干扰能力强。
Based on the average current control technology, an 1 kW single-phase Boost active power factor correction circuit was designed and implemented. The double close-loop control was employed in the PFC systems.The internal current loop controled the input current of the converter so that the input current followed the sine curve of the rectified input voltage. The external voltage loop could achieve constant output voltage. Experimental results proved that high power factor and little current distortion can be realized. Meanwhile, the converter has high dynamic response and strong anti jamming capability.
