i am planning to design a power system of 3500w for my ROV. can anyone help me to do this?
I don’t think it would be responsible to offer advice about designing a system the operates on dangerous high voltages. There are a lot of safety regulations that have to be followed.
Aw, c’mon, be a sport and help the guy out. What could possibly go wrong?
3500W seems a bit excessive for a small ROV, if you could lower your power requirements you can head over to TI’s Webench, enter your requirements and it’ll design it for you.
I just tried a 1600W 400v PSU running from 110-240VAC and it came up with 5 different designs.
But do bear in mind @gcelec’s comments; unless you really know what you’re doing this could be a very dangerous enterprise.
Better to head over to Ailbaba where they sell 600V/3.3kW units for around $300.
