Hi i'm trying to make a tesla coil but in the process of winding the secondary i used an online calculator to calculate roughly the inductance of the secondary and it turned out to be around 0.09 uH for a secondary of 6.6 cm lenght and a 4.3 cm diameter and roughly 850 turns, so i calculated the resonance frequency of the secondary and topload to be around 160 Mhz, since i can't make a 160Mhz generator for now i was thinking of friving it with the capacitor with a spark gap that puts it in parellel to the primary so they can resonate ( hopefully at a similar frequency of the secondary) so to generate a high voltage to charge the capacitor with i designed the circuit on the image wich is simply an astable multivibrator made with bjts an then an h bridge that powers a transformer ( i don't know if driving the transormer with a square wave is the problem but i tought that since the square wave has infinite armonics it shouldn't be a problem becouse one of that armonics will also be at the resonance frequency of the secondary of t1 and the capacitor) but the h bridge doesn't work as intended and i don't get why, there seems to be close to no current in the load ( for now i'm trying without the tesla coil itself ) i also tried with two reversed leds but they don't turn on at all, but using only two mosfets of the h bridge seems to work just fine , but then of course the capacitor would get charged at a slower rate so i think that either i didn't use the mosfets right (is the first time i'm trying to design a circuit with them ), or i got all the idea of the driving circuit wrong.Also i wanted to ask if i should cut off the secondary of the first transformer when there is an arc to let the capacitor and primary of t2 resonate.
Details:
power source : 5v dc
mosfets:IRFZ44N
bjts: 2n2222a
voltage on the secondary of the first transformer(T1) should be around 150 v
rb of the astable :10kΩ
rc of the astable : 220 Ω
c of the astable: 4.7uF
Thanks for your attention
update: i tested my mosfets and they all turned out to be broken, i guess buying them on aliexpress was not a great idea...
anyways i'm trying to make the circuit work with bjts, in particular making the h bridge from tip122 darlington, i made this circuit that works on simulators but it doesn't in reality, i don't knoew what is actually going on in reality because i don't have an oscilloscope to test, so i'm just asing for your help again( second image circuit first row : the two utput , second row: 100 ohm resistor that will later be the inductor, all the other rows are transistor vbe or vce that i forgot to remove before taking the screenshot an close the tab, sorry for that and the general mess in the circuit)
