Gerald, My guess by seriesing two will drop the flux density in each to around 10 kilogauss as each will have 1/2 the line voltage across it. That's well below the bottom of the knee and in the linea

Tony, To be honest, I forgot about those welds. If the welds are close to the ends of the core it wont be so bad as the flux will have already started to bend down into the legs. What the welds do is

John, It's according to what type of rectifier circuit you'd use with the capacitor. For a full wave bridge and capacitor input, the secondary current is from 1.6 to 1.8 times the DC current. That va

What you have where a weld is across the lams is this. If we looked at the cross section of a lamination, the eddy currents would be in a circular pattern inside the area we're looking at though thin

What they used to do on oil cooled transformers, is places some thin wood strips between each layer making a small windown that the oil could seep though. Of course using oil on a regular transformer

Rich, The main thing for any transformer is power in = power out, this in watts or VA. That is minus the losses which is the efficiency. Each rectifier/filter circuit has its own formula to determine
