I had this topic on another forum but we got the boot because we where
told that we where off topic. We had a good thread going on and
somebody told us that this forum might be more appropriate for this
kind of discussion.
I am trying to design a welding machine based on the inverter
principle. So far I have the AC line being fed through a diode bridge,
filtered through a capacitor, modulated through a IGBT "H" bridge
feeding current to a 10 Ohms load resistor. Eventually I want to feed
a step-down transformer and then turn up the power in order to have
sufficient current to weld but I am afraid of the transformer's
voltage kick-back destroying the IGBTs in the "H" bridge. I have made
a lot of tests with LT Spice's circuit simulator and it looks good but
I am afraid of the pitfalls, in real life, that I don't know about. If
anybody is familiar with power inverter might be able to tell me what
for.
Thanks
