How to Convert AC to DC: 11 Steps (with Pictures) - wikiHow· Attach a step-down transformer to the left side of a perfboard. A step-down transformer is a small electrical device that has wires with differing numbers of coils to lower the voltage from a supply to the output. For a simple converter circuit, look for a transformer that's rated for at least 13 V so you can drop the input power lower.Views: 717K
