I have a problem have testing jobs about 100 coils built yesterday a stone ferrite HV transformer on the sec and 4-5 Windungne on the prim. The whole is controlled power transistor by nem small clock generator and nem. My meter shows 600v, but radio or I get net something what ichn wrong did?
have all isolated, and the transformer buzzing in the rhythm of the heartbeat vibrations so with 600V you get 0.6 mm spark out theoretically, which is that you can't see that no wonder...
So either less Primärwicklungen(Schlecht, da schlechtere Übertragung) or more Sekundärwindungen(bessere Möglichkeit, aber auf gute Isolation achten!) wrap up. what you take as a control that fits already. the stress alone can (almost) no air bridge, so you see what brauchste enough power, to the arc in the length to be able to pull.
600V should be sufficient as a combustion voltage there. If you are using a 555 or similar, power amplifier with low on build you a-again stood and if possible the core in both directions magnetize.
I have a transformer 10/300wdg, which depends on a ZVS and eats a whopping 500W. Unfortunately my tungsten electrodes don't take longer than a few seconds it, then they evaporate. (Yes, I have unfortunately only 1mm sticks).
copper and the same are not an issue, pretty much everything under 2mm melts material thickness after a few seconds. (see my avatar, which is a thicker aluklotz + tungsten electrode)
but I digress... in any case more current chase through, how you do it, had to keep trying, but if only n bit sparks is definitely low power output, in the game. If the transformer humming, then I could imagine quite that the frequency is too low. Min. 15 kHz are required to properly control a Ferrite transformer (and then the transformer blows rather than that he hums).
If the frequency is not correct the performance can be so large, yet almost nothing is transmitted. It is possible also that the HV transformer because of the overload on the primary side buzzing? If not enough threads on the primary side, the resistance is too low, then, the wire could lose power by overheating. Try times dear ten turns to use and output more 1000 turns. you could probably already, but with 1kV / 500mA on the workpiece is me n bissle dangerous ;)
lead as thin bars (less than 2 mm) melt away quite quickly, thicker stuff (plates of 0, 5 mm etc) said that unfortunately too quickly off heat. electrical testing equipment
