Good Morning All
I am building a +/- 63volt square wave invertor for AC Tig welding from a high current DC 63volt supply.
I am using 4 x 100amp thyristor in an H Bridge, capacitively commutated by 4 mosfets.
Driving a Purely restrictive load.(I think arc is Purely restrictive)
I want to add some simple shoot through protection for the thyristors
Any ideas or options?
thanks David
