Difference beetween 12V and 24V

Can anyone help me with the following:
In order to build a PMG I've been searching in several places and I've found some very good tips, mainly from Mr. Hugh Piggott. However I've been having a question:
In the PMG, what should I modify in order to my output be 24V or 48V and not 12V??
Is it in the coils or in the bridge rectifiers??
If it's the coils is it in the number of turns, the thickness of the wire, or in booth??
Thank you everyone
Guerreiro

hello Guerriro. the best i can offer here is direct ratio.

to double volt, you double turns and 1/2 the size of wire

to triple volt, you triple turns and 1/3 the size wire

to quadruple volt, you quadruple turns and 1/4 size wire

your amp output will follow the decrease in wire size. double voltage=1/2 amp output and so forth.

easy way to calculate 1/2 wire size is to count up 3 sizes. 1/2 of #14=#17, 1/4 of # 14=#20. to be sure consult a magnet wire chart that gives circular mills of wire size.

if anyone has a difference of opinion with regards to ratio of turns versus wire size, please jump in.

have fun-----zubbly

It could be that wiring the coils in series will raise voltage and in parallel raise amperage, but I have wondered if the wiring size on PMA's is a good indicator of the intended voltage output- probably so.
