| 摘要: |
| 提出了一种具有低输出电压纹波的三态伪连续导电模式（PCCM） CUK功率因数校正（PFC）变换器及其控制策略。在CUK变换器的中间储能电容（过渡电容）上串联一个开关管，使得中间储能电容电压在一个开关周期内存在3个工作状态，进而获得低输出电压纹波和快速的负载动态响应速度。分析了三态PCCM CUK PFC变换器的工作原理，仿真验证了理论分析结果，同时通过一个200 W的实验电路验证了结论的正确性。结果表明三态 PCCM CUK PFC 变换器具有输入功率因数高、输出电压纹波小和动态响应速度快的优点。 |

| Abstract: |
| A kind of tri-state PCCM（Pseudo Continuous Conduction Mode） CUK PFC（Power Factor Correction）converter with low output-voltage ripple and its control strategy are proposed. By connecting a power switch in series with the CUK capacitor，three operating states of capacitor voltage are obtained within a switching cycle，resulting in low output-voltage ripple and fast dynamic load response. The operating principle of tri-state PCCM CUK PFC converter is analyzed and verified by simulation. The experimental results of a 200 W prototype show that the tri-state PCCM CUK PFC converter has high power factor，low output-voltage ripple and fast dynamic response. |
