摘自上文Conclusions： This paper has presented the topology principle and experimental results for a novel high efficiency, high stepup coupled inductor boost-flyback converter. The operation of the proposed converter is similar to that of the active clamp flyback converter; thus the leakage energy is recovered to the output terminal and the switch voltage stress is significantly reduced. The coupled inductor technique employed to achieve the high step-up voltage gain has been investigated and verified. Comparisons are made between the proposed topology and the conventional boost topology. The conversion efficiency is improved with high step-up voltage gain for low power applications. Computer simulation and experimental results have verified the predictions of the mathematical modelling; the mathematical medelling agrees closely with the experimental results. The features of this converter include high efficiency, high voltage gain, low voltage stress on the switching element and simplicity of design.
1、耦合电感作为反激拓扑的变形。与boost相比，耦合电感boost缺点就是输出二极管D2承受的电压应力比输出电压高，当然反激也有这个问题。 2、耦合电感也可以成为正激拓扑的变形，本人没有研究，望大牛补充。 水平有限，个人见解。如有不对请指正。
