simple transformer dc

[foretmark]

In order to get 24VDC using a transformer, I'd like to take a 16v transformer, rectify it and put a capacitor across the lumpy DC (after the rectifier of course). Obviously using a 24v transformer, I'll end up with almost 40VDC. For a 100VA transformer, I have roughly 4a available to me at 24v, and 6a at 16v. By using the cap, after the rectifier, do I still have the 6 Amps available at ~24V?

do enlighten me.

6A at about 24V is approx 144W. Do you think your 100VA transformer is going to be happy about that?

ok, IAC=1.8 x IDC for a FWB. So as long as my load doesn't exceed 3.5A or so, I should be ok...thanks
