I want to create a converter from 1 phase to 3 phase with some detail :
input : 1 phase 380V/1A
output : 3 phase 60V/1A
Can everyone show me how to create it?
 

I'm not sure if this technique exists but its my idea.
First rectify 1 ph supply into dc.
Then use an 3ph inverter to get 3ph ac.
 

For the purpose of building it;
You need to convert Single phase AC to DC. Then by using three phase inverter you should be able to get 3 phase output.

Yes you can do it with transformers that you can find phase shift transformers. Not sure if they exist. I have seen three phase, phase shift transformers though.

Mostly, it would be done by AC(single phase) to DC then DC to AC (3phase).

Are you asking just for the sake of knowledge or want to build one?
