Hello to everybody To begin with, i am trying to built a DC to AC inverter, step up the voltage with transformer at about 500v then use a voltage multiplier to charge some capacitors to about 4kv. I have already built this circuit
but i have adjusted the cap and resistor for 15khz. I need that high frequency cause my voltage multiplier uses 3kV 10nF ceramic caps. The circuit looks to work well but when i made my on transformer to produce the high voltage, (about 500v) transistors starting to produce some whistling noise and began to heating up even without load. Is this behavior normal to transistors ? I am afraid that they will burned. Can i use mosfets instead of those transistors for better performance ? Also, i have seen that other circuits are using a center taped primary transformer, but i have choose this one in order to keep things simple. Is there any advantage or disadvantage compare to this circuit and a circuit that uses a transformer with a primary center taped coil ?
Thanks
