I simply can`t use this program - if I click anything (say "RUN SIMULATION"), PC freezed. I tried re-instalations, etc., but to no avail. I have Windows 98, I don`t have enough knowledge about programing/PC to find what`s wrong. Any idea?

mine's running on Win 98. I wish I could say more. No problems. Perhaps you downloaded an error? try downloading a new program maybe?
regards,
Douglas

Don`t help, I tried a few times. I must find some friend with "accurate" PC to try some simulations. I have 360-0-360 V + 2x5V/3A -300VA toroid, Rpr=3,9 Ohms, Rsec=26+26 Ohms (total R~36 Ohms). LCLC, first choke 10H/130 Ohms, second 10H/275 Ohms. I planed first C=270uF/450V electrolitic, and second 50uf/330V AC motor run cap. If you have some time, please try it, I calculated various ripples/Q/fres/Uout all afternoon "by hand". Load about 75mA, tube 5V4G or GZ34, maybe 5R4.
Yes, I`ll try it these days in real life, but like to calculate/simulate it first...the goal is about 300V output.
P.S. Is anything better with 0,22+0,22uF before and after the first choke, by M. Jones?

With a GZ34 I get an output voltage of 280. First LC stage shows ~300V.

I can run some more variations and post results if you wish.

Huh, little dissapointed, but try some variations on the theme, for example little cap in front of the first choke... Obviously, I need at least 375 or (400V - "Guinevere"!) for 310V out (2A3/6B4G).
In version II, I need about 430V (CLCLC), little first C, say 10-15uF.
In the real experiments with 340-0-340V and CLC I get about 420V/100mA with GZ34.


using some Round numbers... [message #30578 is a reply to message #30577] Thu, 17 February 2005 12:43 Go to previous messageGo to next message

The high DCR of the second choke is costing you. 100 mA through 100R is 10V. So ~300 R, and 70 mA and you have done yourself out of 20 volts. If you could keept he DCR of both chokes to ~150R you'd get your 300V( I think ).

Huh, I know, but thanks anyway... Those are the only chokes I have now. One of these days I`ll solder it all together and try "in real" what I can do with the parts I have...you know, SE project (evil laugh:-))...
