both, the device and the power, should turn on/off

Runaway Pancake


for a project I habe to run a 12V device and have to be able to turn on/off it.
and
...I want to use my arduino to power a 12V converter which convertes to 220V :D if possible WITHOUT anything like a battery and just need to turn on/off it.


By "turn on/off it" do you want to effect the device on/off, power on/off, as with a switch (e.g. a relay)?

Yes, you'll probably want to look at a high-current mosfet transisitor, like those used to drive motors. You could wire the extra supply to a mosfet's source, and then wire an arduino pin to the mosfet's gate to turn it "on" and "off".

You could try wiring that together yourself, but if you're unfamiliar with soldering custom electronics, I would suggest you look at one of the high-power motor control arduino shields.

using transistors is also no alternative?
and if I use a 9V battery plus the 5V from arduino, how will I be able to control all of this?

No way, not possible. The Arduino is great a controlling things, but it's not possible for it to power something like you are asking for.
