Re: To Inductor...or Not to Inductor...

["Eric Chang" <ericchang@my-deja.com>]

 Hi Rich.  A big inductor would help.  Note that
it will be big due to the current it must
handle, not the inductance.  The inductance will
not depend on the current, but only on the
mains frequency and the amount that you want the
PF to be corrected (return harmonics to be
filtered).

There was quite a long thread on this topic
earlier.  Somewhere in the thread is a circuit
by Mark Hanson, some cautions about its
performance by Lee Hart, and an explanation by
me.  I also posted a Perl script for evaluating
the effectiveness of such networks (dangerously
close to violating the list's text only
restrictions).
