How can I change 110 volts AC to 220 volts AC

[KISS]

Yes. But lets find out why you want to change 120 to 220.

You would need a step up transformer. What do you need the conversion for (i.e. appliance, television, etc)? The reason I ask is that a hairdryer will require a whole different type than home electronics.

Here's one suggestion, but a quick Google will result in many responses.
