摘要
论述了采用开关电容功率因数补偿模块改善整流装置的输入电流波形的方法。在对工作原理进行分析的基础上,采用PSpice仿真的方法,综合以提高输入端功率因数和转换效率、降低输入电流谐波含量和输出电压脉动系数为目标,分别对输出功率为60W,40W和15W的具有开关电容功率因数补偿模块的电子镇流器的参数进行优化,得到了具有实用价值的结果。
The method of improving the power factor of rectifiers by switched capacitor Power Factor Correction(PFC) circuit is discussed. On the basis of analysing the basic principle of switched capacitor power factor correction circuit, PSpice simulation is used to optimize the PFC circuit for electronic ballast of 60W, 40W and 15W, respectively. A hybrid index of increasing the input power factor and efficiency and reducing Total Harmonic Degree (THD) and output ripple voltage are used in the optimization. The results with practical value are obtained.
