摘要

介绍了一种利用UC3854实现PFC电路的简单技术。该技术是通过参考电流发生器实现电流峰值控制。升压预调节器的峰值电流降低，降低了电路电流应力，从而使电路元件的额定电流最小化。仿真和实验结果验证了新方案的可行性。

Current stress minimizing control scheme for power factor correction ( PFC ) boost pre-regulator

A simple technique for PFC circuit is presented using UC3854. This technique is about current peak controlling by a reference current generator. Decreased peak currents of the boost pre-regulator reduce circuit current stress and so rated currents of circuit elements are minimized. Simulation and experimental results will verify the viability of the new scheme.
