We have an application for one of our vessels, that has severe problems with the generators and need to be rectified, so that we want to supply the vessel with external power, but the power of the vessel is 440 VAC, 60 Hz, and we have 380 VAC, 50 Hz, so we want to rectify for the voltage and the frequency.

Someone have any other solutions that will be great.

A month ago we had an application almost same as yours, it changed the power from 60Hz/3phase/230VAC to 50Hz/3phase/380VAC.

In such applications, I think a frequency converter and transformer can be a solution:
The frequency converter changes 50Hz/3phase/380VAC to 60Hz/3phase/380VAC, and then the transformer changes 380VAC to 440VAC.
