cool Tom I have downloaded and will check it out, I'll have to track down the LTSpice transformer model too!

Megajocke the 0.1 ohms was a paracitic on the voltage source. The cap (which I scaled up from a different model I had lying around) had ESR set at 0.05 which is definitely too high.

I was referring to Mooly's simulation back there. 0.1 ohms voltage source series resistance would be quite a large transformer.

Osvaldo de Banfield: The OP stated 30VDC at 2A, but what you said sure is correct if the load current has an AC component. (unless it is of low frequency compared to the line frequency)

gootee: Thanks for the link. I think I saw that thread some while ago.
