Ideal bridge rectifier GB

[merlin el mago]

I have such project on my workbench, but are there enough people interested in a 450V at 6A ideal diode ?
Can we reach at least 100 units ?

On other hand, SalignyHV @ 200V is almost ready.

Tibi

Count with me, depending the price several units.

Count me in for 450V version too, but i cannot specify how many yet...

Any updates on these projects Tibi? Potentially interested in both but definitely the 200V SalignyHV. What's the current rating of the 200V version?


Thanks

There must be more interest in order to put Saligny HV in production. Parts are not cheap. I can estimate 50euro for such bridge. Footprint similar to current Saligny.

Here are some specs:
- min ac voltage 18V
- min dc voltage 25V
- max ac voltage 200V
- mac dc voltage 280V
- peak current >100A for <100us
- continuous max 25A
- 2.4W total power dissipated at 10A

Thank you for delivery confirmation !

I used straight pins and bended at 90 degree.

You may use one that is already angled at 90 degree, or solder some wires.

Hi Tibi,
i got the angled pin headers and i am not sure... the holes in the Saligny are, i thing, around 1.2mm. This pin Headers are 0.50mm and for 1A..are they strong enough ?? i have very hard time to find bigger one...advise please..

 

[iTiberius]

Yes, 0,5mm pin headers are more than enough for 1A.

Tibi

 

[Hicoco]

Thanks Tibi, Do you have any recommendation for 3 to 5A ?

 

[iTiberius]

That 0.5mm pin will handle 5A as well. You should worry about your pcb trace more than the pin.
If you want to feel more comfortable, use Cu wire with bigger section.

I was worry about because the datasheet give 1A maximum. i will use the CRCRC PSU board from Prasi and believe me the PCB trace are huge....

I am interested in a couple of the 200 and 450V versions.

 

[JOIMONF]

Same here

 

[s610adam]

Same here, likely more in the 450 version but 200 as well

Here is a quick draw on how such solution may be implemented using UCC24624.
The juicy part is mosfet selection.

Hi Tibi,

Reading the data sheet it appears that if the input frequency falls below 9kHz, the chip assumes that the input converter is off and it shuts itself off as well. That would mean it wouldn't work with 50/60Hz mains.

Am I correct?

[iTiberius]

You are correct, Jan.

TEA1995T can be a replacement. Almost same schematic.
For this topology, you may use two individual controllers as well.

Tibi

Thanks Tibi, you are like a SR-wiki! ;-)

Hello Tibi. If there isn't sufficient interest for you to run GBs for the HV versions will you make a schematic/gerber files available?

 

[iTiberius]

Saligny HV will be available for sale by the end of July. Still working on PCB and some parts fine tune.
I'll estimate first batch based on you input, therefore fell free to express your interest.

Tibi

 

[merlin el mago]

I'm interested. 200AC is tx output? What about the price?

 

[iTiberius]

Saligny HV will be at least 50euro.
