If the power went up you would have created a device with greater than 100% efficiency, aka a perpetual motion machine. In any conversion scheme power in will always be greater than power out. Do you want to buy one or build one?Originally posted by demonkid@Mar 27 2006, 12:21 AM
ok i want to convert 36volt @ 9 watts to 12 volt's
where would i get a converter at and 1 more ?
if i did convert the 36 volt to 12 volt wouldent the amount of watts go up also since i am
going down in voltage.
thx in advance.

Lets assume your talking DC voltage here....
I also think you may mean "Amps" or current, not the "watts" going up.
If you use a Switch Mode regulator/converter, then yes, you should end up with more current, and only a slight reduction in the "Wattage" (i.e high efficiency, low power loss).
If you use a linear regulator such as the 7812 then you will get no increase in current, as 2/3 of your "Wattage" (Power) will be wasted as heat in the regulator. It will get real hot, and need to be mounted on a heatsink so that all that wasted power can be used to warm up the box it's all mounted in... i.e. it will be Inefficient, and with 36v going into it, will be running at (or possibly above) it's maximum ratings.
thx and could you give me the links to the web sites? i'll google them but if i cant find them i wanna have something to come back toOriginally posted by windoze killa@Mar 27 2006, 05:24 PM
Powerbox, Amtex and Lambda all produce modules that do exactly what you want. Havwe a look at their web sites.
