AC/AC Converter For Naval Application

Click on the Products & Suppliers tab at the top of this page.Then enter your requirements.You will have to choose the supplier yourself.

Thank you , Lyn.

Here's the deal. You list them all and I'll delete the bad ones for you. How about it?

Okay.
I will try to search in Products and suppliers as Lyn's advice.

and let's you help me then.

Might be helpful to know whether this is for 100 watts or 10 megawatts. It does tend to narrow the field down a bit. Desired input voltage range and output voltage would be nice too. Fixed output frequency output or variable? Input frequency range? Isolated or non-isolated output? Hold up or ride-thru requirements? Above deck or below deck? How about cooling? Air, liquid, conduction, radiated? Operating temperature range? Non-operating temperature range? Humidity? Salt-fog? Sand or dust? Vibration requirements? Shock? Rad hard? Redundant N+1? MIL-STD-1399 compliant? MIL-STD-704 compliant? MIL-STD-1275 compliant? HERO compliant?

It's in a range 10kW to 300kW.

and input : 380Vac 50Hz

Fixed Output : 440Vac 60Hz (or maybe other)

This is all i know now. Where can I study more about differenct in each type? please advice.

It appears this needs to be triple phase, but not sure what you mean by ..."440Vac 60Hz (or maybe other)". I am not sure at all you will find something that can either be 60 Hz, or 400 Hz. Why not use a 50 Hz 300+ kW rated motor to power a variable speed drive to your genset? Not sure you can find that in MIL spec item either.

If you are trying to electrocute a navy ship, forget it. If you are trying to make an invisible navy ship, be careful what you wish for. If you are simply adapting US Navy standard shipboard power to the available power at European (or other 50 Hz) ports of call, then you should not be having a problem finding this, as I do believe it has all been done before, many times.

The above link is for a company that has modules that accept single or triple phase input power to triple phase output at the potential you specified, and offer tunable output frequency from 40-400 Hz (crystal oscillator stabilized), in blocks of up to 36kVA. It appears these are available only as MIL spec grade equipment, as their application page is entirely for military applications. I don't know how you missed this site, given all I had to put in the google bar was "AC/AC static frequency converters"

Its in a navy junk shop probably best finding it.

The Royal Navy, of course. What a silly question!

OH SHIRLIE?

Most major power supply manufacturers should have Mil spec versions you are after.

define what is meant by "static" freq conv. do you mean electronic as compared to a motor/ generator set? and do you intend to convert 50 or 60 hz to naval power, which afaik is 400 hz?

Yes. because if we use MG set. and once MG set have a problem. we have to cut the ship.

but for the static type. we can replace only module by module.
