That is a puzzle John, the best DC I can get out of that with kcalc, assuming a perfect bridge rectifier feeding a capacitor input filter is 179 volts & change. Assuming a 127 volt, more or less standard AC input that is. > On 12/25/2015 12:34 PM, Dave Cole wrote: > > On 12/25/2015 5:59 AM, John Thornton wrote: > >> I wonder if I should put that filter at the beginning of the AC > >> circuit or just ahead of the bridge rectifier? > > > > I think I would put it prior to the transformer that feeds the > > bridge rectifier, if that makes sense. > > > > That AD VFDs tend to broadcast serious noise back into the AC line. > > I've seen the VFD noise go right through AC to DC power supplies. > > > > Dave > > > > > > > > -------------------------------------------------------------------- > >---------- _______________________________________________ > > Emc-users mailing list > > Emc-users@lists.sourceforge.net > > https://lists.sourceforge.net/lists/listinfo/emc-users > > ---------------------------------------------------------------------- >-------- _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
