就以全电压范围输入的反击变换器来讲好了,output:12v/5A,工作频率80KHz,一次侧感量以500uH为例,变比40:7;
工作方式连续or断续?D=?

12V5A,全电压输入.DClink电容取100u Vdcmin=58Vdclinkv_ripple=69V Dmax=0.48 RippleFactor=0.25(连续模式) f=45k Vro=54V(次级反射电压) Vdsmin=Vdcmin+Vro=429V Idspeak=3.75A Idsrms=2A CoreEI40(材料待定) Bsat=0.3T
MD设计中,知道电流为梯形波(连续模式),计算出Idc和Iac值.
由 Idcpeak=3.57A
D=0.48
知:Ip=3.57A
Im=2.142A
Irms=1.992A
Idc=1.37088A
Iac=1.45626A
(Idc和Iac 计算变压器交流损耗和直流损耗)

首先打开MD
选择磁芯TDK EI系列.
工作频率<100K,工作温度假设100度,选择PC30-LF-100C磁芯材料.注意选择Winding Shape--Round.
Flyback 我们选择Inductor模式.
