I recently got into a conversation with an electronics old-timer (he was on
the Apollo project etc).  I had just helped his wife to select a PC/AT clone,
and we got to talking about power supplies and stuff.  Suddenly I find out
that I don't know how a switching power supply works.  Could someone with the
necessary knowledge give me the baby-talk -type explanation so that I won't
get stuck in such an embarassing way the next time ;-) ?  Be gentle, I'm only
a computer hacker with limited (and long-past) electronics experience.  Post
only if you have iron-clad knowledge of this.  No "I thinks", please.
