I have tested a transformer as a choke and a toriod autoformer
as a choke in a choke input power supply. I Iloaded them to ~80% of there ac current rating with darn good results.
I think my results were about 5% different than calculated using
Duncan's power suply designer. Now this may not work in all cases but in the 2 cases I tried it sure did.
