OLD THREAD Simplistic Mosfet HV Shunt (The Simpler Simplistic Design by Salas)

[jameshillj]

Yeah Vancao, these things happen sometimes, unfortunately.

QH has one in stock and is sending that out to me, so we have a happy ending and the Dac will end up much neater than the 2 sets of "hypnotize" boards.

Not intending to stir things up, just was unsure what was happening - all now resolved.

Hi Quanghao, did you send PCB's to me ? I have been waiting for some time now. I send $55 to you via paypal on May 3, 2010.

Thanks

Still nothing, at this point I need only one board. Let me know how we can resolve this.

Can tell me please???
Thanks

No, I did not get anything (zero). For my project I need only one PCB.

Did anyone receive any of QH's boards?

Also a somewhat related techical Q and forgive me if I should post elsewhere:
anyone tried this implementation to get a regulated B+ of 330V using Vin ~ 380V?

Yes! you can use Vin 380V - v out 330V. But
Note:
1. R 3 = 68K/5W
2. R4 = 200-220K

you can try do it!
Thanks

 

[phi70]

Thanks QH

May I ask the R3 R4 references, which schematic are you referring to?
Seems like there are many posted on this forum,
Thanks.

QH, on the boards I got from you it has irf9610 on the printing instead of the irfp9240. Is the latter the latest version? I'm only starting to put together and just realised this. I built according to the Salas '09 BOM see that there are a few changes.

What are the benefits of the changes? Am correct to assume that I can also do the latest on my boards?

Thanks

Hi! that is EX;
So IRF9610 can change with IRFP9540!

PCB's

I just ordered 2 PCB's (IV stage PCB and Simplistic Mosfet HV Shunt PCB) from your website, I hope they will arrive fine. Don't worry about previous order.


Thanks
