How to convert -12V into +5V ? i.e., a -ve voltage into +ve

How to

Solutions depends on output power . Flyback DC DC , switched capasitors ...

I think use a diode to and a res can do this function.
use diode to product the current direct to gnd,selecting res apropriately whitch the current thru could product +ve

Thanks. i would like to convert -12V into +5V. I would be happy if u can still elaborate ur suggestion.

use the inductor and NMOS or PMOS by the controler of invter.

Sorry, sir,
I conserate your problem as ac-to-dc simply,i think FLYBACK convertor can solve your problem

Hi.
I was attached one file for this reson.
