Hi can anybody, please, explain the ALG value for me as given in this PIEXPERT desing?
Core specified as gapped to ALG of 332nH/T2, with Np=31 yields Lp= 319uH, Nominal primary inductance is then given as 339uH, and under schematic page transformer propeties third value is given of 305uH. We found by measurement that Lp=305uH works well, does it mean that the core should be gapped to ALG of 317nH/T2 rather then 332nH/T2? Why then discrepency in the PIEXPERT file or am I missing something? Thanks very much.
