Thanks Everybody
&
Sorry for late(i was so busy and in pressure because of project)
A NEW PROBLEM
at first the wants me to build high voltage (12KV) sine wave.
I built a transformer for this and a sine wave, but i need too power in low volt side of transformer (high current).
So I was need to parallel bipolar transistors.
Then now they say just want 12KV ac.
Now i can use mosfets too and parallel them and use square wave(on and off)instead.
i think irfp460 is good.
If I do, i can use old transformer but i need new circuit.
My question is which circuit is better?
half pole, full pole, using top ics, pwm,using each transistors for half period or...
PLEASE HELP
if this project ends i shoud build inverter 500watt {60~78V DC => 50V 60hz AC}
:roll:
but
tanque weri mach
with ALL your helps
