三路交错式PFC在空调器中的应用

An interleaved three-channel power factor correction controller designed for air conditioner

为了提高空调的输出能力和空调的功率因素,减少对电网的影响,使用一台5匹输出能力的空调作为PFC的负载,研究了三路交错式PFC的设计方法,分析了三路交错式PFC的工作方式以及该工作方式的优点。通过计算分析以及实验验证,表明了设计方法正确并且三路交错式PFC很好地改善了空调的功率因素。

In order to improve the output capability of air conditioner and power factor, reduce the impact on the grid, using an air conditioner as Power Factor Correction controller＇s load, studied the design method of interleaved three- channel Power Factor Correction controller. By means of calculation analysis and experimental verification, this paper shows that the improving the design method is correct and the interleaved three-channel Power Factor Correction controller is good for power factor of air conditioner
