The quasi-resonant topology But to say the least, the first driver I have built with this topology had an AC flyback and an input power supply rated just 60 watts. Hello, Jozef! The audio in can be convinced to get a 1V signal 10Hz and to amplify it up to 4kV? Sorry for so many questions. Would it be any problem if in 555 2n3055 flyback of the ohm resistor was one of ohms? Hey i have the same flyback how can the flyback be a problem? Oh, and of course I do not get nothing on the output of the transformer.

No, only one, but i tried with another to check if the problem was IRFP. OK I found the problem, i post here so people with the same problem can make it work. The solution is to run 555 2n3055 flyback one power supply i use now 9V battery and the mosfet and the primary with another I use the lab power supplyDO not 555 2n3055 flyback to connect the ground of the two power supplies together, Now it works!!!! I dont get it. Question feed. Why do most people who read this thread miss your statement that you used a high voltage Toshiba Mosfet instead of a 2N?

Maybe you should have corrected your schematic before posting it. Your circuit doesn't need R5. Dec 16, Hi everyone, I'm trying to build a flyback 555 2n3055 flyback circuit. The circuit you posted only adds complexity with very little to gain.

Quote from: nshin on 12 Jun, It may be a while 555 2n3055 flyback I can actually contribute to the design but I hope to do so in the future. It uses a power transistor 2n and two coils: a primary and a feedback on a flyback ferrite core.


Schematics and details:. You can use 2 x 2n transistors in a better circuit that provides more power.


As you can see in this image, it was soldered directly to the transformer. Please refer to this schematics R?

555 2n3055 flyback I forgot the value. Realy I got it on my need,I want to make a plasma ball. Thank you I'm not using the rectifier GI at all, initially I used a set of heavy high speed diodes but it's been running fine without them.

I didn't have any 20K pots on hand for the pulse width adjustment so I experimented with 10k and 50k. Sign up for free See pricing for teams and enterprises. This 555 2n3055 flyback is among the simplest, with just six components it will be able of delivering high voltage with a strong enough 555 2n3055 flyback for various experiments.

Read this document 555 2n3055 flyback safety! The transistor used in this circuit should not have a voltage rating higher than V, due to the higher base current needed of higher voltage rated transistors, this might in some cases cause problems where the self-resonating circuit can no longer drive the transistor. At voltages higher than 12 VDC input, the components will dissipate a lot of heat and the 2n transistor is most likely to burn as it is not rated for more than 15 A and it has to be derated even further for case temperatures above 25 o C. The driver is built on a piece of vero board with multiply resistors to obtain the needed wattage rating, this is far from optimal as the load sharing between them is horrible, to ensure better sharing.

The voltage across the coil will take any value required to keep the current running. This is why you can easily create sparks with a coil, a spark is simply a current flowing at a very high voltage. This circuit gives a burst of pulses to fire 2 SCRs, when pin 4 is taken to 12V the SCR is turned on, to use this circuit you need 12V short pulses phase shifted with respect to AC sine wave on bridge.

To drive ignition coils is to use a timer pulse generator. A generates a square wave output that triggers the 2N Adjusting the two potentiometers and the value of the capacitor will change the frequency of the output. The charger consists of two stages: The first is a capacitive voltage doubler, which uses a timer IC driving a 555 2n3055 flyback of transistors connected as emitter followers, which in turn drive the voltage doubler proper. The doubler has power resistors built in, which limit the charging current. The second stage is a voltage regulator, using a regulator IC. Its output is applied to the battery via a diode, which prevents reverse current and also lowers the voltage a bit. The resulting charge voltage is about The 2n transistor is mounted on a 30 x 10 cm aluminium profile, this is just 10 nF to nF, nF was 555 2n3055 flyback to work the best for my flyback transformer.

This is a high voltage flyback transformer driver. It uses a flyback, a 2N transistor, a ohm resistor.
