Hi guys!!! i cam across the 13.8V 20A power supply project by Santa Cruz http://www.electronics-lab.com/projects/power/002/index.html Fisrt, thank you very much for this informative project! second, i have some question, i have a transformer who get 220v as input and on the output it give 17~18v 400VA my question is are this transformer can handle 30A right? 33.3A (400/12) so if i am did not wrong, how can i use this transformer in this circuit? i mean to get 30A output? what should i change? Thank you very much, and sorry for my poor English.
