Mosfet for 10KV @ 10A (500KHz)rating for the inverter application

Former Member

Hello Everybody!!!!!!!!

I am working on a concept that requires a high voltage(>5KV) inverter application, the load current will be (5-10A) and the switching frequency will be 500 to 1000 KHz i need suggestions on the availability and their pros and corns.I must be thankful if any body has worked on it previously and can share some info about it.

    This is waaaaaay late and I am sorry that those other guys gave you the run around, they should have led with this rather than poke and prod into your project which is yours to share at your discretion, but the truth is they are right. 5A is not a small current for a 15kV source. Personally I've never seen a human operated welder need anywhere near this kind of power. If you are trying to make a handheld type welder I would recheck your source material as I am fairly certian either your voltage or current requirement that you are asking for is significantly higher than it needs to be. If this is for an industrial application then that's a different story. I could see something like a massive plasma cutter mounted on a robotic arm cutting up 1/2 inch steel plates needing something like this, but if that is the case it is not wise to get this advice from a forum but rather a licensed professional. If you already have the product or device you need to power then I recommend contacting the supplier for advice on how best to supply it the necessary power. Good luck if you are still working on this, and stay safe.
