Wow that is realy a nice project you are doing.
Mainly my interest of coupling Paul's controller with igbts is to have a higher voltage safety margin as I am obsessed about safety margins.
Also if I intend to up the power it will safely handle the burden.So far it seems that only IGBTs can do it with ease at least voltage wise correct if I am wrong,albeit at some cost such as heat /efficiency, although using a module seems much easier to have a cooling solution.
Just my idea,usually they ain't so good, so that is why I need much help from any body here who surely have more experience than me.
Many thanks and keep up your good work.
