Accordingtomyexperiencedcalculation,它的感量在300uH,Np=30Turns.我是考慮到90Vac最低波動電壓來計算的(i.e.100Vdcinput).Ifyouonlyneeds100Vinput,thentheinductancecanbegreaterthan300uH,(350uH-500uHmax.)Itdependsonyourspecificrequirementfromcustomer.Butyoumustconsiderhowtokeepthebalancebetweenefficiency&TemperatureandEMIduringdesign.
