摘　　要：将扩展状态平均法理论应用到单级功率因数校正(Power Factor Correction,简称PFC)变换器的研究中。建立了带抽头电感的PFC变换器的等效电路模型,并推导出反映电路主要特性的状态方程式。用解析建模法建立了Matlab仿真模型,并对电路参数进行了优化,通过实验验证了解析方法的正确性。The theory of extended state-space averaging method was used to research the single stage power factor correction （PFC） converter,an equivalent circuit model of the PFC converter with a tapped inductor was established,and the state expressions reflecting the main characteristic of the circuit were deduced.Matlab simulation model was established by using analysis and modeling method,and circuit parameters were optimized.The analysis theory is approved completely by experimental results.
