| 摘 要： | 为DSP控制的功率因数校正(PFC)变换器提出了一种新的采样算法，它能够很好地消除PFC电路中高频开关动作产生的振荡对数字采样的影响。尤其是当开关频率高于30kHz时，所提出的采样算法能有效地提高开关抗噪声性能。最后将此算法运用到一台2kW的PFC变换器中，实验结果证明了该算法对于分析、设计和调试所有含开关的数字采样电路均有实用参考价值。

| Abstract: | A novel sampling algorithm is presented for DSP controlled power factor correction (PFC) converters, which can successfully avoid the influences of the oscillation brought by the operational high - frequency switching in PFC circuit. The proposed sampling algorithm can greatly improve the switching noise immunity, especially when the switching frequency is above 30 kHz. Finally a PFC converter with 2kW based on the proposed sampling algorithm is implemented, and the experimental results prove the practicality of the proposed novel sampling algorithm in the analysis, design and debugging of all digital sampling circuits with switching. |
