I want to double the voltage of a stepper plus rectify it to DC, Answered

I want to double the voltage of a stepper plus rectify it to DC, how can I integrate two below circuits or should I, voltage doubler also rectifies fine?

I`m not american, so what is a stepper plus?!
Also what kind of voltage you want on DC output.
Your both schematics are wrong... in first are 2 groups of diodes, and in second, there is chaos, you shoul have them bridged as in first... but only one.
But tell us more. You`ll need transformer in AC in for diode bridge.
So, what AC voltage goes in circuit and what DC voltage you need in out.

Neither am I. Stepper is a step motor, used in precision movements but when spin it generates around 2.7v 200ma , if you use both coils it can give 5v.
If I connect a voltage quadrupler like below it will give 10v or two of those on each colil 20v and that, can charge batteries.
my question is can I combine the two or do i need to? perhaps the voltage doubler will also rectify?
thanks
