How to rewind the transformer under the LBP?

Question

Do it yourself

There is a transformer OSM-0.4UZ with a primary 220V and a secondary 0/5/36. He's at 10A.
I'm going to rewind it so that there are steps, for example, 5/12/24/36 volts.
It is necessary that each section be approximately 70V * A
As far as I understand, after the diode bridge, the maximum voltage for the 5V winding will be (5-1.5) * √2 = 4.95V
Accordingly, at a current of 10A, each winding should not exceed 6.5 volts .
Thus, we will have steps 6.5/13/19.5/26/32.5/39 (wind 4.5 turns)
Or still shift to normal 5/12/19/24/36 ???

Answer 1

Isn't it easier to take 36 volts, filter, equalize and lower the pulse to the desired value? Or 5 and 36 at once. Then one converter will roughly lower from 36 down to 5 volts, and the second, more accurate, will operate with everything below 5 volts.
I'm all about the fact that you won't get tired of winding this trance? I would score, for example ..
If you need a LBP, as stated in the topic, then in addition to voltage, you need to implement current control.
