摘要

提出了一种改进的不连续导通模式单相升压功率因数预调节器的小信号模型。该模型是利用注入功率变换器输出的平均电流方程的近似推导出来的。在进行小信号扰动后，得到控制-输出电压和输入-输出电压传递函数。开环和闭环实验结果验证了分析的正确性。

A representative small-signal model for the single-phase discontinuous boost PFP [power factor preregulator]

An improved small-signal model for a discontinuous conduction mode (DCM) single-phase boost power factor preregulator (PFP) is presented. The model is derived using an approximation for the average current equation injected into the output of the power converter. After making small-signal perturbations, both control-to-output voltage and input voltage-to-output voltage transfer functions are obtained. Open and closed-loop experimental results validate the analysis.
