Power Transformer Inrush Current Limiter
Benta:
jbb brought up a great point:
A tertiary winding on the transformer.
Letting the tertiary winding build up the magnetic field at much lower power than the main primary (using maximum voltage switching with SCRs, as I suggested earlier), cutting in the main primary supply at a later point is easy.
Downside is, you can only start the transformer without load.
An interesting problem indeed.
