摘要

建立了一种用于控制实时升压功率因数校正(PFC)电路的大信号平均模型，并对其进行了线性化处理，得到了PFC电路的小信号模型。使用小信号模型进行交流分析，揭示了PFC电路小信号动力学的新结果。通过对200w PFC原型电路的实验测量，验证了分析结果和模型预测。

Modeling and small-signal analysis of controlled on-time boost power factor correction circuit

A large-signal average model for the controlled on-time boost power factor correction (PFC) circuit is developed and subsequently linearized resulting in a small-signal model for the PFC circuit. AC analyses are performed using the small-signal model, revealing new results on small-signal dynamics of the PFC circuit. The analysis results and model predictions are confirmed with experimental measurements on a 200 W prototype PFC circuit.
