555 Timer-Based Flyback Transformer Driver. Get a high power supply for this test. Don't use an expensive lab power supply for this test. I modified your circuit slightly and separated the timer circuit from the power MOSFET and Flyback. So, now the input into the primary is 20Vdc. I get the 12V, 18kHz output from the timer, but once I. Nov 19, 2006 - Identifying the High Voltage Return on a Flyback; Method 2 Testing Procedure. The typical flyback or Line OutPut Transformer (LOPT) consists of two parts (you. For example, various versions of the flyback used in the Apple MAC Plus. A function generator or a 555 timer based circuit will also make a.
Flyback Transformer - Any would work but newer one are more robust and can output a higher voltage. They can be taken out of a CRT TV or you can buy a new one 2. MOSFET - Any mosfet will work but the drain to source voltage should be at least be 200v and it should have Rds(on) lesser than 200m xCE xA9. I used the IRFP460 but I dont recommend you to use it since it has a Rds(on) of 270m xCE xA9.
I recommend to use IRFP250. Heatsink - You will need a heatsink the mosfet since it will get hot. I used an intel cpu heatsink through which I drilled a hole.
The heatsink you are using must be big. Fan - You will need a fan for the heatsink since it does get very hot. Resistors - 2x 10k resistors 7. Capacitor - 1nf ceramic capacitor, A large electrolytic capacitor for smoothing the positive rail, A polyester capacitor of capacitance 0.68uF or higher with a voltage rating of 200v or higher 8. Breadboard or pcb - To build the circuit on 9. Power Supply - I used a 12v 10 amp power supply 10. Wires - Thicker wires will be needed for the primary coil and mosfet connections.
This circuit can be power with voltages higher than 12v, but when you first power it up power it with 12v or lower to find if it works or not, if it doesn't work then switch it off as fast as possible. If it doesn't work try reversing the connections of the primary. If can be powered with up to 16v, if you want to power it with 16+ volts then you will have to power the 555 timer and the primary coil with different power supplies as the max input voltage of 555 timer is 16v. A 9v battery can be used to power the 555.
I used an arduino with a sd card module to play music on the flyback with music on a sd card, so this is the new schematic. For this code to work you have to download the TMRpcm library from this link To make it work: 1. Format the SD card 2. Take your music file and convert to a WAV file with these dimensions - Sampling rate - 16000 Hz Channel - Mono Bit resolution - 8 bit 3. Rename your WAV file to 'music' 4.
Put it in your SD card Use this website to convert to WAV files - Attachments.
I have just one question: Very bright arcs, very powerful flyback. June 29, at The current seams to be small. DONT try to use my design i messed up on it. Uploader: Date Added: 3 August 2008 File Size: 48.53 Mb Operating Systems: Windows NT/2000/XP/2003/2003/7/8/10 MacOS 10/X Downloads: 16481 Price: Free.Free Regsitration Required Everything else it the same as your schematic. Anyway, thank you for share your circuit and your experience. If you can give me a help I audio modulated flyback it. High voltage enthusiasts, who are familiar fyback the classic NE flyback driver, will notice the foil capacitor across the primary winding, audio modulated flyback really makes wonders.
Aamir June 1, at The sound quality is low due to the way the audio modulation is implemented. My mosfet still heats up though. Audio modulated flyback notice you are using a flyback but is it possible to use an automotive ignition coil adio place of the Flyback?
Flyback driver #2: NE quasi-resonant – BOGIN, JR. Dont worry about the amperage rating of your power audio modulated flyback as long as it can supply a minimum of 12V 2A, this circuit will draw more power with a higher duty cycle and less power with a lower duty audio modulated flyback, but we are talking around 25 — 50 Watt depending on your supply voltage. So when I Plug the 40v supply to the mains and turns the on, it draws a lot audio modulated flyback current. I looked in Google for Plasma Tweeter Circuit and found it. January 30, at Find out how much current it can output and calculate if its sufficient to drive the IRFNs gate at the frequency you want audio modulated flyback.
High-pitched whine, strong hiss and vast amounts of ozone are produced, high voltage wires are moving on their own, nasty static charges build up on everything conductive, strong ionic wind and corona discharge are felt even 0. For music modulation the thin arcs work the best. This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register. Thaks for your help flgback.

High-power 555 Flyback Driver For Mac Download
The only problem is, the sound quality is Really really bad. So far I have only used the original primary v. I did find some errors I made though. Audio modulated Flyback Driver If the MOSFET heats up a lot, it might be running in linear mode and thus the is not audio modulated flyback enough drive current. I live in a very rural area so online shopping aufio not available, the electronic shop takes a month or so to restock their parts.
Sorry, I forgot one thing more, that configuration of the schematic it is not a audio modulated flyback pwm because the frequency is modified too in the control voltage pin of the number 5. Normal multistranded moeulated as f. I know the dangers as well. Fire in the hole! DONT try to use my design i messed up on it. I got so much help from this site.
I hope driving the flyback this way will also translate into music on audio modulated flyback output of my tesla coil. Irf510+ne555 timer flyback driver audio modulation Arduino Air Bonsai Levitation. In other words turn that khz arc on and off say times a second so as to simulate a lower frequency arc?

January 7, at Mine i audio modulated flyback music a a terrible screech.
