摘要 在详细分析固定关断时间(Fixed-off Time,简称FOT)控制原理的基础上,提出了将FOT用于Boost PFC时的方法。仿真验证了该方法的可行性,并利用DSP作为控制核心设计了一个Boost PFC电路。仿真和实验结果表明,该方法能有效减小输入电流谐波,提高功率因数。 This paper analyzes the principle of the Boost PFC circuit based on Fixed-off Time control,simulates the circuit and designs,an experiment taking DSP as the controller.The circuit works in CCM and is controlled by peak-current control method.The simulative and experimental results show that this method can reduce the input current ripples and increase the power factor effectively.
