    Hi Helmut,<br>
    <br>
    Very nice work!  We look forward to future updates.<br>
    <br>
    I saw your other post about reluctance to use a "primary side"
    design because of safety concerns.  I completely understand and
    support that.  Some years ago (quite a few actually) as a young
    design engineer I was involved in the design of some switching power
    supplies.  I was at first surprised by the strict spacing and
    isolation requirements between primary and secondary.  As I gained
    more experience, I came to really appreciate the thought that went
    into those rules.<br>
    <br>
    73,<br>
