# Is it possible to convert 3 Phase 220V to 110V without use of a transformer?

I am living in an area where line voltage is 220V. If I have access to all 3 phases, is it possible to create a "socket" with output voltage of ~110V, without use of a transformer? This is primarily a thought experiment, rather than a project with definite scope.

• "using only those phases and maybe some simple components as caps or inductors" You mean like a transformer? Jan 3, 2014 at 16:25
• Nope, the whole point is not to use a transformer. I have no idea if it's possible. I am thinking maybe something like shifting one of the input's phases so that the phase to phase voltage could be 110V.

• What is the reason for not wanting to use a transformer? Jan 3, 2014 at 23:01
• A 2:1 autotransformer is the usual way of deriving a 110 VAC supply from 230VAC. Why do you seek a transformerless solution? (Is this a practical problem, or a thought experiment?) Jan 7, 2014 at 7:18
• A transformer is big and bulky. If it's possible to not use a transformer to do it it would be interesting. It's a thought experiment for now but if it's possible I would want to try it.
