L6562 Transformer Calculate Tools

1.Design Specifications

Vinmin=85VAC Vinmax=265VAC

Fl=50Hz

Vo=24VDC

Vaux=16V

Δvop-p=1V

2.Pre-design Choices

Fsmin=50KHz

Vor=100V

η=85%

3.Preliminary Caculations

Vpkmin=Vinmin×1.414=120.19V

Vpkmax=Vinmax×1.414=374.71V

Po=Vo×Io=19.2WHISEQ2000

簇绒机Pin=Po/η=22.58824W

Kv=Vpkmin/Vor= 1.2019

废钯碳回收钯技术F1(Kv)=(0.637+0.0046×Kv)/(1+0.729×Kv)=0.3424655

F2(Kv)=(0.5+0.0014×Kv)/(1+0.815×Kv)=0.2534329

F3(Kv)=(0.424+0.00057×Kv)/(1+0.862×Kv)=0.2085841

F5(Kv)=(0.5+0.0014×Kv)/(1+0.815×Kv)=0.5

4.Operating Conditions

Ipkp=2Pin/(Vpkmin×F2(Kv))= 1.483136A

Irmsp=Ipkp×sqrt(F2(Kv)/3)0.431074A

Ipks=2Io/(Kv×F2(Kv))= 5.252774A

Irmss=Ipks×sqrt(Kv×F3(Kv)/3) 1.518458A

5.Transformer

Lp=Vpkmin/((1+Kv)×Fsmin×Ipkp)=736.071uH Lpreal=730uH

n=Vor/(Vo+Vf)= 4.065041

(a.)Choose Transformer Core

Ae=54mm2

(b.)Transformer Caculations

Np=Lp×Ipkp/(Ae×ΔB)=

84.23561T Npreal=77T

Ns=Npreal/n=18.942T Nsreal=19T

Naux=(Vaux+0.6)×Nsreal/(Vo+0.6)=12.82114T Nauxreal=13T

发热涂料Lg=0.4×π×Npreal2×Ae/Lpreal=0.550861mm
