Would you be referring to, "This do not matter much when is used with two diodes for rectification." I first understood that he was referring to traditional rectification. Are you saying it refers to use with the 4321? Or am I entirely missing your point? If I'm not missing your point then it's good news and I will proceed. Ron |

It says that you can use 2 ideal rectifiers in your situation BUT that both windings need to be connected right. They usually are connected right with CT transformers but if you have the accidental other type you will have smoke.

Do not connect anything to the secondary side. Plug in the transformer (work safe!) and now measure between the outer connections and ignore CT. If you see the specified voltage x2 you can continue. If you see a very low voltage they are connected wrong for the LT4320 solution.

OK. I have a 120 VAC in / 84 VAC out transformer with CT. Secondaries are definitely in phase. I can use this transformer with 2 x 4320 to feed +/- 60 VDC rails on my amp. If this is true I can go ahead and push the button on my Digi-key order. Thanks for the help getting clear on this! (If I'm not clear on this, let me know.) Ron |

Hard one still as the LT4320 has a absolute maximum input of 80V AC. Well I don't know, I haven't used them like that so I can not give hard evidence. In fact I just finished my first PCB's but boy they measure very well! I would take the challenge as I see the logic behind it when reading tvicol's post but things can be damaged if it does not work out OK.
I think you need to PM tvicol as het has quite some experience. Or the member that had them ending up in smoke (some posts ago). I would be very sorry if I misinterpreted and gave you non optimal information.

I guess the best way is to try it out (carefully) and see what happens. I may also buy a smaller transformer, 12 VDC or so, and see if the idea works at those low voltages before trying it on my larger transformer. Ron |

You need two separate secondaries each with his own bridge. Regards, Tibi

Saligny HV is performing above my expectations. It was tested in 4 amplifiers. Two Class A, one AB and one D. Sonic improvement was substantial in all of them. So far any circuit that got synchronous rectification got far better performance. Regards, Tibi

If so, I think that with their current capacity (25A?) I could run my two CLCLC power supplies off one Saligny HV? I guess they'll be quite expensive and not readily available so that arrangement might suit my pocket and avoid me being too selfish by buying more than I actually need. What will be the means of purchasing them - through your website? Cheers Last edited by nautibuoy; 21st October 2019 at 12:35 PM. |
