Successful TPU-ECD replication !

[ronotte]

@Darren,

1 - Yes, the other 2 coils must be disconnected. This makes the comparison much more easy. Note: the situation with 3 coils & 3 freqs are too much complex (...for scope trigger also).

2 - Yes, exactly so: use 2 switches in parallel and drive one switch at 55kHz, and one switch at 60kHz.

3 - When I scope the ECD I always have my scope ground on P.S. ground, and then either scope the ZERO or PHASE terminals or both .....I can also scope differentially the 2 points...(without connecting the scope ground).

Darren, I thank you so much that kind of simulation, it may shed some light on ECD scenario.

@Darren,

forgot to say that this is just the initial simulation. I'm thinking, if you have time and want to follow me, to drive you step by step (following my real operations) into obtaining the features I observed: Seed, Peak's conversion, sinus appearing, etc

OK Roberto, thanks for the confirmation...and you're welcome.

I'll run some tests tonight (10am here at the moment).

I'm going to try and run some sinusoidal frequency sweeps also to see if I can find any sweet spots and resonances.

Unfortunately, at the moment I don't know how to do frequency sweeps with this sim square generator, or even if it is possible.

Hi all interested to ECD,

what it follows is the test report for the new Otto's CC design.

The new transformer has been built and set on my test-ECD in order to be able to make any kind of test. Said ECD is for test purposes only and anyone can ask me to do tests. Please remember that this run is with ONLY the new CC energized.

PS: I forgot to say that in pdf the voltage swing on load is always ranging from 200 to 500V and in pic2292 and Pic2294 you can see the Seed very well.

Hi Roberto,
well done.
What does your power supply exactly read as the
used voltage and current.
Better use a 100 nF foil cap directly across the power supply output plug pins
so the RF pulses will not influence the power supply.
also an iron or ferrite core wired around your red and blue supply cables
could work as choke lowpass shield versus your power supply.

Many thanks.
