大家好,我现在在做隔离CUK型变换器的DC-DC开关电源设计,在隔离型CUK的变换器的设计中,请问大家怎么确定各电感电容的大小呢,我打算输入为220V 50HZ 的家用电压,输出为10V 2A的功率,开关选用D44H10频率为50KHz的,希望大家不吝赐教!

把最终电路图呈上来呀
这是我主电路电路图,大家看一下参数选的对不对,我不知道参数选取的公式,只是估计了一下,大家看一下,有谁告诉计算公式方程,附上来把!

1.C1(200000uF),C2(200000uF),L1(45mH)取值太大了些吧.2.当Q关断时,初级L1和变压器你是怎样续流的?3.C4上面的10是什么意思?
我重新做了一个,不知道能不能正常工作,你帮我看一下我的仿真波形对不对,谢谢拉
