摘要
提出一种新型充电泵高功率因数AC/AC变换器拓扑结构。该变换器具有电路结构简单和采用PFM控制方式的特点。文中分析了电路的工作过程及取得高功率因数的条件 ,给出了电路参数设计指导 ,并通过实验证实了理论分析的正确性。
A novel charge pump ac/ac converter with power factor correction is present in this paper It features symmetrical circuit topology and ordinary PFM control way The input Inductance current frequency in the converter is twice as large as in CIC-CPPFC,because two charge pump capacitors are charged and discharged alternately in the converter Input inductance ripple current quantity is reduced The operation principle of the converter circuit and high power factor condition are analyzed The design considerations of circuit parameters are discussed Experimental verifies theoretical analysis It can attain the goal of realizing high power factor without specific controlled IC
