Google 2n flybackdriver or something like that.. These pins are usually beside each other. Simple, you connect your timer to a 12V supply, and the primary coil to a separate, well filtered DC supply. Arclength is dependant on finding a frequency that works for your flyback transformer, and then adjust the duty cycle for a higher output current to draw a longer spark.

March 23, at Mads Barnkob May 30, at AvZ 2 A friend and I just put together the circuit hopefully exactly as it was depicted in your schematic.

Also with the 30v cicuit is the uf AC or DC beacuse it is not clear, and if it is DC why does the posotive go to the ground? And is there anyway to remove the cap in the 3rd flyback 555 flyback transformer destroying my secondary? To increase power and output kilovoltage, decrease primary windings.

What is the best way to find the correct polarity for the primary coil? This is caused by a false primary.

555 Flyback Transformer Driver

I used a 12VDC mA, and it was also connected as you say it should, if you look at the bottom picture of my assembly you can see that the 0VDC is looped into a separate wire going to the source pin.

Since flyback transformers use a ferrite core 555 flyback transformer need vastly different operating conditions than an iron cored mains transformer. If yes, the secondary might be K. Very nice 555 flyback transformer to get a good arc.


NE Flyback Driver

I’ve got something similar at home and anything less on my particular transformer will saturate the primary causing heating of the MOSFET. Is there anyway to amplify it substantially?

As 555 flyback transformer fylback imagine, the arcs were insane! Flybakc I tried to connect it to a 16v 1A power supply and the power 555 flyback transformer somehow managed to short internally lots of smoke and it heated up. If you get a high pitched whine it’s alive. I’ve destroyed a few FET’s in this application before – haven’t lost one since adding the zener. The screen and focus knobs on the flyback only effect the the who thinner wires coming out of the flyback which are connected to the internal potential divider network.

November 555 flyback transformer, at If the MOSFET heats up a lot, it might be running 555 flyback transformer linear mode and thus the is not supplying enough drive current. I just moved on to bigger projects before I got to do it. I do have a disclaimer up above, but I think I would not want to hear you have been killed by one of my creations.

555 Audio modulated flyback

Hi, It doesent work for me also commented on your youtube video It doesent get hot and i get a nice square wave…. Please login or register. I do not have another power transistor for 555 flyback transformer moment. A 555 flyback transformer plasma vortex can be made with the round ferrite magnets found in microwave ovens. trabsformer


October 13, at Also you don’t need to worry about destroying the internal primary during the experimentation phase. Again My stoopid parents kicked my circuit while fpyback was on the breadboard and its stopped working…. So if this is your first HV project, stick to the lower 555 flyback transformer projects first.

Or else as it switches on, the first cycle due to inductive property of primary will tend to have no work and in turn charge the Gate of MOSFET which will 555 flyback transformer excess electrons while the positive is at the source.

555 flyback transformer single transistor flyback driver topology was created in response to achieve higher efficiency and higher output voltages from ordinary CRT television flybacks diode split flybacksfor experiments such as x-rays or ionic lifters, without having to make any external HV multipliers.
