Make sure you have C1’s polarity correct, and also BR1. Please remember that most of the site rules still apply here. I checked everything over again today and found none but two heads are better than one, so if someone spots a screwup please let me know! Contact If you need assistance, please send an email to forum at 4hv dot org. The voltage and frequency can each range over a wide scale depending on the device.

This is high voltage threat it with respect. Computer Science This is where to post everything computer-related, such as hardware, software, and programming. Please read our Disclaimer and Policies page for information on your rights and responsibilities regarding this site.
In modern computer displaysthe frequency can vary fyback a wide transfoormer, from about 30 kHz to kHz. I was able to power a small 20cm Spark Gap tesla coil Using these dc rectified flybacks to charge primary tank capacitor.
Uspring 3 years ago. The low voltage output winding mirrors the sawtooth of the primary current and, e. Archive Discussion This board is transformeg pointing out good threads that are found in the archives, located at and. If you would like to see something changed, or you just have a suggestion, post it here. Dear Jonathan, Thank you for this circuit. Unfortunately, this server costs and we rely on the help of site members to keep 4hv.
The MAX is the reason for that.

Make it out of 22 insulated hookup wire, closewind make each turn touch the next turn about 12 turns directly onto the core, the exact number of turns is not critical, neither is its location on the core. One advantage of operating the transformer at the flyback frequency is that it can be much smaller and tansformer than a comparable transformer operating at mains line frequency.
The rectified voltage is then used to supply the final anode of the cathode ray tube. The high frequency used permits the use of a much smaller transformer. Learn how your comment data is processed.
I know how to fix it if it fries ; Safety This circuit has the capability of seriously shocking you. Please remember, this board is for archive-related discussion only! Most likely there will be oscillations, screeching noises, high input current and not much output, etc.
Aron’s H-bridge is gorgeous on a board, mine is slapped together on a heatsink. Conundrum 5 months ago. Arcstarter Sun May hvgy.com In particular, very high voltages are easily obtained using relatively few turns of windings which, after rectificationcan provide flyabck very high accelerating voltage for a CRT.
Gate on the left, drain in middle, source on right Dark Current Thu May 07 Draw an arc off the high voltage output of T2. But it sure looks weird.
This includes Marx generators, cascades, flybacks, and more. If you have a question about the wiki, or would like to register, use this board. So far, staccato hasn’t helped sparklength much, but then again, we just got the thing working.
The operation is simple The is wired as an astable and the capacitor is charged only through the 4,7Kohm trimmer notice the diode and discharged only through the 2. If you need assistance, please send an email to forum at 4hv dot org. Also another way to do this is use a gate drive IC.
