This web site requires that javascript cd446 enabled. Click here for instructions. Sun May 01 I am building this circuit. And with the tables on the datasheet for CD I am getting center frequency of a little bit less than 6MHz. Tesla coils as big as mine cannot work at such high frequency. I have a Tesla coil secondary that is a little different than the one that the author used for his circuit. I datawheet like to use this Secondary.

For this reason I would like to play around with the values of the R1R2 and C1 to make sure that this circuit produces the resonant frequency of my secondary. The resonant frequency of my secondary: The resonant frequency is about KHz but my calculations may be wrong. How big does the current in the primary circuit need to be? How thick should the wires be in the primary side of this circuit? Would attaching a thick primary coil, made out of a telephone cable with all strands tied together in parallel make sense if I am using 0.


Should I redesign my circuit to use banks of smaller capacitors instead, to make the total diameter of xd4046 leads greater? Antonio Tue Aug 30 Tue Jun 12 Uspring Fri Sep 02 Thu Jul 07 The link you provided doesn’t seem to work for me.

I used How big does the current in the primary circuit need datsaheet be? Max primary current depends the choice of primary inductance.

You don’t want to exceed the capabilities of the FETs. They are not exaclty the same thing. I need to obtain some frequency that matches my Tesla Coil secondary that I bought: How do I design the primary? Does it need to be thick? Conductors on the circuit board that lead to the primary are not very thick.

Capacitor leads are less than 1mm Thank you. Uspring Mon Sep 05 They seem to be similar in terms of the frequency diagrams. Steve Conners web pages seem to be under construction. I’d use the same primary inductance he did which I don’t knowscaled by the frequency. Your primary copper wires should be at least 4 or 5 mm in diameter.

Use JavaTC to calculate secondary res frequency or better measure it. For the design of the primary also use JavaTC. It will also tell you the effective copper resistance of the primary in cluding skinn effects. From there, with the max current of the primary, you can get an estimate of the power dissipation in it, which will help you to choose a thickness. I believe that all the Tesla magic that puzzles historians of science was in his now obsolete PLL circuitry. He built powerful systems that were capable of changing their frequency to tune into other sources of frequency.

My CD is different from the one you referred me to. I thought of buying a different IC but decided against it. I want to replace 12K and 16K resistors with K potentiates connected in series with 5K resistors for safety. I would also like to use a variable capacitor. Do I need to make the primary work in resonance with the secondary? Which part is easier to make adjustable? Do I need to make a primary coil so I can change the amount of engaged coils on it?


Should I use the same datashedt – 2 X 0. Uspring Tue Sep 20 No, the primary isn’t a resonant tank in a SSTC. An adjustable primary would be nice, so you can adjust the load to the bridge. Making a primary is more difficult for me. I assume that one 0. I need to measure or calculate the LC of the primary using this data.

Would a multi-strand telephone cable make a good primary? I want to tie all the strands together datashedt the ends and use it. I need the generator to work in the range of frequencies that the primary LC datashert in and the secondary as well? Secondary coil will always drift around. This is the whole point of PLL as I understand. Double pendulum — Is Tesla Coil an electric analog of this mechanical system?

Mon Aug 29 Registered Member Joined: On the datesheet of CD there are graphs on page 4 and 5. Tue Aug 30 Fri Sep 02 I get MHz range according to the table.

I agree with Antonio. Cd40466 Sep 05 I believe you can also use the TI chip. Wed Sep 07 Fri Sep 16 Tue Sep 20 Mon Oct 03 I bought the secondary and I may wind several identical secondaries for an experiment.
