is it possible to convert 60 hz to 220 V 50 hz with a computer? any one have any circuit diagram and code? or any document or link about this conversion??
The OP mentioned nothing about size - neither physical size nor the "size" of the load under consideration.
Yes, rotary converters do tend to be quite large (both in terms of size & power).
The OP can't expect to get only relevant answers to an inadequately-specified question!
In fact, such a poorly-specified question may be seen as an open invitation to suggest the most outlandish solutions that could possibly fit the minimal details given...
