摘要
双Boost PFC变换器在半桥逆变器的UPS中得到广泛使用,其输出电压纹波的质量直接关系到UPS的稳定性。采用功率匹配的方法对双Boost PFC变换器的输出电压纹波进行深入研究,得出了该拓扑输出母线电压二次纹波的变化规律和决定纹波大小的影响因数。仿真及其实验结果验证了理论分析的准确性。
Doubler Boost PFC is widely used in the UPS （Uninterruptible Power Supply） with half-bridge inverter, and the quality of this converter＇s output voltage ripple is critical to the stability of the UPS. Through power matching method, the output voltage ripple of doubler Boost PFC is analyzed deeply. Therefore, the varying pattern of the ripple is summarized and the main factors of effecting ripple is obtained. The correctness of above theories is verified by the simulation and it＇s results.
