If you can’t find the 120/150/170 devices easily you will still get good results with the STP20N95k5 which is definitely available on AliExpress...Last edited by JulesP; Yesterday, 08:13 PM. -

Hi Rodolphe,
I’m not an electrical engineer but my understanding on this is that all MOSFETs have an internal, also called body or...Last edited by JulesP; 11-21-2022, 05:05 AM.Leave a comment:

You don’t need a high current rating and the DSEI12 will not work with the 150 or 170 as it will breakdown at a lower voltage than those with the...Leave a comment:

Hi Ron,
This is probably not the right thread for this discussion but while you’re here I will share what I can.

The DHG1011800PA diodes were easily got from Aliexpress for about 7 Pounds for 10pcs with delivery. For the FETs try the attached.

Hi Rodolphe,
Yes, I have now tried the120k5, 150k5 and 170k5 with the 1800 diode. There is small improvement on CoP between the 95k5 and...Leave a comment:

Hi all,
As some of you are keen to have a go at a build and have been asking about the main components etc., I attach the wiring diagram...Last edited by JulesP; 11-15-2022, 04:30 AM.Leave a comment:

I might try and measure the peak voltage and rise time with no ferrite cores and see what happens. So far using 1.5kV instead of 1.04 and 1.1kV is beneficial...Leave a comment:

Hi Rodolphe,
The graph shows the measured CoP when the voltage across the coils was adjusted while keeping the PRF etc the same. The reason...Last edited by JulesP; 11-12-2022, 09:02 AM.Leave a comment:

While I'm putting material up, I have just written a sort of guide for those who have become 'stuck' and unable to get the CoP over 1 for this type of...

Hi Rodolphe,
As you may know from Gary, I built a cap dump circuit for my energy harvesting project as part of a test rig to confirm or refute...Last edited by JulesP; 11-06-2022, 12:04 PM.Leave a comment:

An energy harvesting project
Hi all,
For the last three years, I have been working to obtain unequivocal evidence that a Bedini-style generator can harvest energy from...Last edited by JulesP; 11-01-2022, 04:44 AM.
