Re: [TCML] DC charging reactor

[Ibrahim Khaleel <xbox1900@xxxxxxxxx>]

Hello Roger, thank you for the kind response. 
Would you please give a hint on the behavior of SSG if used with a full wave 
rectifier and a smoothing Cap? how to expect the firing point and the breaks 
rate in such a design? are you also calculating the smoothing cap @ 10% ripple? 
and how the chock time constant would be taken in consideration? do you have a 
working formula to predict the maximum charging voltage in tank capacitor?

I really appreciate your help and guidance. 
Have a nice day!

Ibrahim

Hi Ibrahim,   I have built several DC Tesla coils using neon sign transformers 
with SSGs but I have used a full wave rectifier followed by a filter capacitor.  
For a charring reactor I have often used the secondary of another neon sing 
transformer.
        These Tesla coils tend to have a very high break rate and produce 
shorter but more flame like sparks.  They are awesome and well worth building if 
you can find all the parts you need to build one.

Hello every one!

Am planning to build my first DC TC of 20 kW throughput. Am using 15 kV / 30 mA 
NST. Any info in this regard is most appreciated, especially in how to calculate 
the resonance charging reactor. Is it possible to use a half wave rectifier to 
charge the tank cap ( am using SSG)?. Would the BPS rate be @ 50 in this case, 
since the voltage appears only half-cyclic (10 msec.), providing I employ a 
d-Q-ing diode?

Thanks in advance for advising.

Regards
