CCM模式BOOST和SEPIC功率因数校正电路对比分析

对比分析了BOOST和SEPIC两种单级功率因数校正电路。通过对电路参数的设计，使得两个电路都工作在电感电流连续模式下，并且具有相同的功率等级。通过实验分析了两个电路在不同负载以及宽输入电压范围时的功率因数值、总谐波畸变率、效率以及输出电压纹渡系数上的优劣性。并以此为依据，分析了两个电路在实际应用中的价值。最后，以LED驱动电源为实际应用，验证了分析结果的正确性。...

Summary:对比分析了BOOST和SEPIC两种单级功率因数校正电路。通过对电路参数的设计，使得两个电路都工作在电感电流连续模式下，并且具有相同的功率等级。通过实验分析了两个电路在不同负载以及宽输入电压范围时的功率因数值、总谐波畸变率、效率以及输出电压纹渡系数上的优劣性。并以此为依据，分析了两个电路在实际应用中的价值。最后，以LED驱动电源为实际应用，验证了分析结果的正确性。

This paper presents a comparative investigation of single-stage BOOST and SEPIC power factor controller. Because of the careful design of parameters, the two converters operate in continuous conduction mode and have the same power level. A comparison among the two proposed topologies in terms of power factor, total harmonic distortion, efficiency and output voltage ripple factor is also performed. The value of the two converters in practical application based on the analysis is also presented. Finally, a LED driver was built to verify the correctness of the analysis result.
