Using the new 2012 Shigaclone to create a killer high end transport

[TheGimp]

A line powered SMPS has the advantage that it uses a small transformer and has low power dissipation.

Designing a quiet SMPS is a challenge, but not impossible. Both radiated and conducted noise are an issue.

Good layout with attention to grounding will alleviate most problems.

The remaining conducted noise (and ripple) issue can be addressed in part by using a SMPS whose output is 1V higher than the target voltage, and then use a low dropout low noise linear regulator as a post regulator. Although this is a bandaid. A good design will not have issues.

This addresses the differential mode noise, but not the common mode noise.

Common mode noise is best minimized in layout. A common mode filter can be used on the output, but is not a good solution as it imposes it's own voltage drop (I*R).

Hi TheGimp
Do you think that, what you explain is better than a lineair ps.?
And can you make a basic drawing for the shiga 2012?
A direction to pcb for a smps ?

Hi,
Will this link be a sample of a future ps for the shiga 2012?

Doesn't work for me either.

The forum thinks is an diyAudio site page,
Just cut and paste it in a new tab/window.

Hi yoaudio
Nothing personal, but what the forum thinking I don't care.
The link have no mistakes.
Click on page title in post 16 and follow the steps.

As shipping started, I will try to add here information about our boards, soldering, mounting and testing.

Please do not expect from me to be very responsive. Beside my daily job, I need to prepare kit´s for shipping, mounting and also delivering.

What you don´t know is that we are already on the third version board. First and second have been test boards.
During the initial tests we have performed many major modifications and obvious we had to redesign entire board.

Tibi

This is a response on the messages I have received.
All Shiga mounted and tested are RoHS.
On all kits we use Cynel RoHS solder with 3%Ag.

For those who are looking for the best, IMHO Mundorf is one of the best solders available on market.

Also, an inexpensive and very good soldering station is Vellemann VTSSC50N.
