(OP)
i have a 13.8 kv motor. is there any inverter can supply that MV motor in the market? if not what is maximum MV available?

I know Toshiba offers 4kv inverters.
Presumably a stepup transformer could be used between inverter and motor? At least I don't know of any problems with that approach other than cost.

I don't know the exact contacts for this equipment but I am certain that the US Drives & Power Products Group in New Berlin WI can help you.
Their number is 800-752-0696.

There are all sorts of high voltage systems used with railway traction, some are even ac with regenerative braking.

The only manufacturer I know of that makes a true 13.8kV drive is Robicon, now a part of Siemens. Robicon 13.8kV drives link The problem is that 2.45MW is somewhat small in that voltage range so you may end up with a larger capacity than necessary with a nameplate that says it is smaller.
As far as I know, all of the others (ABB, Toshiba, GE, Alstom, and even Siemens prior to buying Robicon), do it by using transformers on either side and a lower voltage (4.2-6.6kV) drive, which adds significant losses to the system. That kind of system works, but makes it even more expensive because the output transformer must be specially designed to function in a variable frequency environment.
Also, IMHO you should definately stay away from someone like US Drives who would do it by transforming down to 575V and back up. Do the math. At 2.45MW, the current at 575V is going to be astronomical!
