| 摘 要： | 本文论述在闭环反馈控制下,输入环节工作在不连续导电模式（ＤＣＭ）时单级功率因数校正（ＰＦＣ）组合变器的稳定性,讨论通过脉冲宽度调节使变换器的电压能够维持在期望的电压范围之内的条件,以及条件的输入电压主动态范围和负载变化范围,并采用上述方法对一个ＰＦＣ ＤＣＭ ｂｏｏｓｔ－ｂｕｃｋ变换器进行了理论分析与实验研究,实验结果结果表明理论分析的正确性。

| Abstract: | The stability of a closed loop single stage Power Factor Correction(PFC) intergrated converter with a DCM input part is analyzed.The criterion by which the output voltage can be maintained within the desired range by Pulse WidthModulation(PWM) is obtained.The input voltage range and the load current range are also discussed.A PFC DCM boost buck converter is investgated as an example.The analysis is proved by experimental results. |
