| | | | | | | | | 我刚来论坛,请教蓝天一个问题,Riley电流模型的补偿斜坡周期为Ts,也就是在电感电流上升和下降阶段均加补偿,占空比调制器增益Fm=1/((Se+Sn)*Ts),从PWM比较器输入端两个比较信号波形小信号分析,怎么得到这个Fm啊 |

| | | | | <<Current-Mode Control>>
In 1990, Dr. Ray Ridley published a PhD dissertation that brought an end to over ten years of fierce debate about how current-mode control systems should be analyzed. The resulting model accurately predicted current loop instability, used average models for the part of the circuit where it applied, and sampled-data analysis for the current-loop phenomena. A simple approximation then produced results that were very easy to use.
This 200-page book, downloadable by chapter below, covers the history of current-mode control and modeling, detailed analysis, practical application examples, and PSpice model listings. Complete unabridged details from the PhD dissertation are included. An abbreviated summary at the end provides quick design assistance for those short on time.
