Hi guys
I would like to have your opinion about the linked suply I drawn. It' s more of a practice and Learning point of view than a official design or what ever. When speaking about high voltages, I speak about voltages used in tubes circuit (preamp, compressor, etc.). I know tubes don't require regulated supply and lot of time, a simple RC filter stages is plenty enought, but again, this is simply a kind of homework I would like to test.
So, it's based around a TL783. I figures a Vout of 300v, just for the exemple. Vin is 260v x 1.414 = around 370v. Vout - Vin = 70v. Tl783 requires between 1.25v and 125v so I'm well between.
The spec sheet speak about a ripple red of 76db. I add some filtering in hope it will help reducing that value closer to 100db and up. Is it overkill, not recommanded, or I could strap some more filtering?
Thanks guys
