# Electrical energy transfer

Crazymechanic
Hi I am thinking of ways how to transfer electricity so that I can separate the phase magnetically or otherwise, Ok we all know transformer is one way to do it but it's big with mains frequency, other would be pulsed DC in an smps , but that's is already a very tried idea, is there any other way of for example separate the mains phase so that I would end up with something that i can safely put through rectifier and use ?
How about some sort of mains conversion to light impulses via laser or somethin and then back to electricity conversion? Ok I understand I am going Star trek now but still is there something like this even economically and any other way possible?

That does not make sense.

Very inefficient (10-20% for electricity to laser light, if you care about efficiency, and maybe 50-60% back to electricity).

What do you want to do at all?

I recommend that you pick up a basic electronics book and read it over thoroughly to understand electricity and electronics before trying to come up with new power transfer methods.

Oh I'm sorry just my english isn't that great so about the magnet thing it was meant that for safety in a transformer the primary windings are physically separate from the secondary windings.Just that the size if operating mains 50/60hz is pretty huge as we all know it.

I was thinking about building a PSU from thyristors or something like that but then there is the problem of the safety because the mains phase isn't separated.

Sorry, but your posts are virtually impossible to understand.

'transfer', whatever that means, has nothing to do with phase. Electricity can be distributed in one or two or three or more phases...see for example

In addition, a capacitor and a inductor will each individually alter the phase between the voltage and current. A resistor does not cause such a phase change.
See for example:
