Ideal bridge rectifier GB

[merlin el mago]

I might well want a second!

If you want I reduce mine order to only 1 unit, please let me know?

 

[Jazid]

I don't NEED two, but I would like another, so if you would prefer to have one, Felipe, then I will happily take the other, but if you would prefer two I will wait and take my chance, after all I signed up for only one!

 

[nautibuoy]

Ten was the minimum order qty. Tibi has indicated (off forum) that he can deliver more than the ten so you can both keep your two and we can keep taking more sign-ups for a while.

GB for Saligny HV;

nautibuoy - 2 Saligny HV
Jazid - 2 Saligny HV
ste - 1 Saligny HV
Luca72c - 2 Saligny HV
Rinman77 - 2 Saligny HV
merlin el mago - 2 Saligny HV

Total = 11

If you're interested copy and paste the list to a new post and add your name and requirements to the bottom of the list.

Thanks Ray, great effort BTW [emoji4]

Mouser will deliver to me 200 mosfets in late November.
I'll be able to make only 50 Saligny HV, so any number between 10 and 50 is fine.

Tibi

Really I need only one, signed two to reach the minimum order for the GB

Thanks Ray & Tibi

Are you still planning on building a higher voltage version for tube amps?

 

[nautibuoy]

No problem Felipe.

We can leave this open for a while to see if there is any more interest and we can sort out payment, distribution etc. closer to when Tibi can supply.

High voltage and low Rdson mosfets are very expensive, far more expensive than many tube rectifiers. Beside this, tube people like tube glow and "soft recovery".
Sorry, but my answer is no.

...tube people like tube glow and "soft recovery".

I plan to use the Saligny HV in front of a CLCLC power supply for an SE-OTL tube amp project.

Well, give me 1000 people like you, so I can justify such project.

I don't think I'll be much help Tibi, my B+ requirement is only around 160V.

I woul be 1 more 😉

Hi Tibi,
I was looking at your EvoTtronix website and you seem sell the low current version is that correct? The site says minimum order for EU is 10units, is that correct?
I am in the EU and I need 4 maybe 5. At a later date I need 2 HC versions. I am really waiting for these unit’s

 

[iTiberius]

Hi,

Yes, Saligny LC is still available.

Regards,
Tibi

Please note that Saligny will work with center taped transformers (and center taped used as main reference ground) only when both sections are in phase. This was discussed here.

Thanks to a very observant friend who noticed the frequency of ripple, the mystery shrouding the weird synphase connection has finally been revealed 🙂

It is perhaps worth warning any adventurous synphasers that in this mode the 4320 works as a parallel half wave rectifier with the obvious increase in ripple. It may be appropriate for this info to also find a spot within the first post of this thread.

The 50Hz ripple can be seen in both simulation and measurements.

In the standard unipolar connection the 4320 applies out of phase control signals to the opposing fets in the bridge, emulating the behaviour of a standard diode bridge. In the synphase connection this changes and the opposing fets get synphase signals at their gates, effectively working in parallel.

Below is the 50Hz ripple waveform from the synphase simulation. In the standard connection this is of course 100Hz.

On the plus side this is an elegant way to achieve half wave rectification without passing dc through the transformer secondary.
