2n3055 flyback driver? Answered

Is there a better transistor to use instead of the 2n3055 because those things break easily and are somewhat expensive.

Flyback transformer problem?

I have recently dismantled an old CRT monitor i have had lying around for ages to get the flyback transformer. I have been trying to get the correct pins to using methods found on the internet none of which have seemed to work i have found what should be the primary coil and have applied the current and placed the high voltage output in front of each pin to try and find the high voltage ground, this has not worked so i have applied the current to all of the pins in every combination and still i am unable to get it to work. Please help me.

Flyback powered Tesla Coil?

Hi. I am trying to build a Tesla Coil, and there are few thins I'd like to know. First, I built this PWM (made a few modifications, IRF530 MOSFET and 10nF ceramic caps instead) and connected it to a self wound primary of my fuh29A001V flyback, and it works perfectly, sparks and stuff. Can this power my Tesla Coil? Next, if it can work, how do I calculate capacitance needed for my tank capacitor? Miloš

Troubling Flyback Transformer Pins

Hello,       I'd like to request someone to share their knowledge about their "flyback" knowledge or experiences with me since I'm having trouble finding the primary coil pins with my flyback transformer. I'm constructing my own HV power supply and I decided to go through this tutorial.       I've read much on the web and found the 0v output pin of my flyback. The problem is .. I couldn't find the primary and secondary since I'm using an analog multimeter and the tutorials on the web are all digital..       When I test the pins with my multimeter set to ohm range of x1, I do not get a pair of 1 ohm pins but instead I got the result of "Continuity" when I test on following pins, they seems to be connected but none of the pins show to 1 ohm.. and thus I've adjust the Ohm Adjustment. The results are Continuity 1 : 1,2,6,8 Continuity 2 : 3,4,7,10 No Continuity: 5,9 Pin no 5 is 0v output..  I've attached the pin number diagram at photos... my drawing and actual pins.. Have you got any idea to find out the primary coil? I've also attach my driver from CFL.. Thanks

Dismantled a CRT - Usable flyback transformer ? Answered

I've been reading up on Jacob ladders and tesla coils for a while now, and decided to try to make a Jacob ladder (the tesla coil just looks scary and advanced) I've taken a part an old CRT. And I was wondering if you could tell me if it looks usable.  I'm wondering slightly if I broke it when I removed it from the 'plate' it was stuck in. Pictures will show what I mean. Sorry about the bad focus on the pictures. Taken with a phone, and it was slightly too dark for it to be able to take good pictures. The brown cables looks like it's just fast in the flyback transformer, but I did not remove it. I tried to get a good picture of the text that was on in case it means anything to anyone.  Also, what I can gather by looking at this is that the red cable is the high voltage cable, and the low(er) voltage cable is either the grey, or white one. - Is that correct? Thank you very much for your attention, and thanks for any replies. And this site is amazing. I'm just amazed at how creative people are.  Oh, and please let me know if I posted this in the wrong category Zaek.

Do avalanching diodes "latch up"?

While working and revising my flyback driver design, I had one of the 1N4148 diodes that I was using as protection get cooked!  (it seemed to fail short circuit) I have not tested to see if the MOSFET survived yet. Obviously the diode needs to react fast and handle avalanching energy well. Any suggestions? are some beefy schottky diodes suitable? Also, does making any ordinary diode go into that avalanche or zener reverse breakdown region cause it to potentially lock up and conduct for a period longer than the EMF spikes I'm dealing with? Or with any sort of hysteresis (like when using neon lamps)? Originally my wimpy glass 1N4148 diodes was wired in parallel directly across the MOSFET drain and source reverse biased. However, carefully examining this tesla coil schematic,it appears that there is both a forward biased diode in series with the MOSFETs, and another reverse biased diode(s) in parallel across the MOSFET & diode. It does not look like a bad idea given one the reverse biased diodes can shunt EMF spikes that are too large while the other isolates them from the MOSFET. My only concern is how lossy that would be at 12V operation.

Anyway i can only get 0.5 cm arc from the flyback, and i dont know what to do to make it larger, i know that the 25w cfl can do better. Any suggestion? Sorry for my bad english.
