IGBT module plan

I want to keep it simple

this module looks pretty good for a gate driver (with DC DC converter inside)

not too expensive - $38USD each

how about two of these for the h-bridge

here is the datasheet

maybe they are too slow.

if 30A is enough, then maybe an IRAM is the neatest option:

New Controller

Time to start thinking about a higher voltage controller

It would seem that I only need to switch the high current (armiture) with a single switch.

I would prefer to use an igbt module

here is someone making a driver board for it.

and someone else

then I only need something small to switch the field windings

maybe a module like this:

cant find it at the moment but there is a three half bridge module that I hope I could just use one of them (can be found in 75A which would be about the right size)

these can be purchased from this shop on ebay:

use these gate drives

http://www.rell.com/resources/RellDocuments/SYS_21/vla503_01.pdf

and these dcdc converters
