glumor functionality

Google, "frequency conversion"

There are several ways to do it - none of which particularly involves a "computer"

If the computer have enough capacity, then it's possible.

But not possible in the way you probably want to.

A generic "computer" is quite good at playing with signals. But they normally don't contain any UPS hardware so all it can do when it comes to electrical power is to convert mains power into the low-voltage needs the internals has.

If you have enough skills to build a converter that can convert 110V (?) 60 Hz to 230V 50Hz, then you should also have the skills to know that a generic "computer" isn't a good starting point.

Note that some AC/AC converters doesn't even make use of a micrcontroller, except for maybe presenting status information. The actual conversion may be handled by a switch chip and some form of feedback loop. Unskilled designs may result in great hazard risks - fire, human injuries, damaged equipment, ...

Some don't even use any electronics at all!

BTW: what is "glumor" ?

A normal transformer just changes the voltage. It can't change the frequency.

For "normal-size" equipment, I don't think there are any products that doesn't use any electronic. Rotary Frequency Converters are normally quite large

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...

;-)

I would assume you want an inverter. Convert the AC to DC then convert the DC to AC at the new frequency. An if the question is can a microcontroller be use the control the output of the Inverter the answer is yes.
