| 摘 要： | 本文叙述了功率因数校正的基本原理和常用的方法，分析了各种方法的优缺点，并在传统APFC基础上进一步提出了一种应用于变频空调的新型功率因数校正控制方法。该控制方法的主要特点是在输入交流电压瞬时值高于输出直流电压值时可完全关断开关器件，停止斩波，只有在输入交流电压瞬时值低于输出直流电压瞬时值时才进行斩波；这就使得系统在获得比较满意的功率因数的同时，降低了对开关器件的要求，减少了系统损耗。

| Abstract: | We analyze the methods of PFC and discuss their respective features. Based on those, a new control method of PFC used in air-conditioner is introduced. The most difference of this method is that it won't work while the output voltage is lower than the input voltage. It makes a high power-factor and reduces the requirement of the system. |

| Keywords: | power factor correction pulse-width modulation average-current control |
