这里给大家推荐另一个参考文献[4],它对d1和d2时刻分别加入小信号扰动,从电感电流出发一路推到output,最终对flyback建模出了和[1]的一致结果(对应于Buck-Boost)。看起来会更加直观,也是一篇值得细读的优秀文章。 [1] 2001TPE Jiansun. Averaged Modeling of PWM Converters Operating in Discontinuous Conduction ...
A new modeling method for flyback converters in DCM is proposed in this article. On the basis of the method of state-space averaging, using the new "duty ratio constraint" and the modification matrix M, the modified averaged model is derived here, then the nonlinear full-order model is ...
DCM flyback on the same core type and size and have the same number converter because the presence of a RHE' zero in the of primary and secondary turns. Due to the smaller L, former's power circuit transfer function dictates feedback the DCM transformer thus possesses the larger air gap....

2. The switching converter controller of claim 1, wherein a flyback signal is observed from the switch-mode converter and wherein the finite state machine responsive to comparisons made by the comparator, turns off the switch and observes an off-time duration of the switch based on the flyba...
Figure 4. Ideal discrete-time small signal model of SCB controlled flyback converter. The converter is modelled as a controlled current source that charges the output capacitor and load, and 𝐺𝑣𝑖(𝑧)Gvi(z) denotes the discrete-time transfer function from output current to output volta...
