一种用于高带宽计算机V-Core稳压器应用的新型多频小信号模型

A new multifrequency small-signal control model for high-bandwidth dc buck regulator is proposed. The describing function approach is taken to model the duty-cycle modulator, incorporating the effects of not only the modulating frequency $f_{m}$, the switching frequency $f_{s}$, and the two sideband frequencies $f_{s}-f_{m}$ and $f_{s}+ f_{m}$. This model is significantly more accurate than the ...
