Sinewave tracking filters in power conditioners

[japlytic]

In two power conditioners I have handled, I believe the following as per attached circuits are the sinewave tracking filter section:

L1/L2, C1 and BR1 (BR1 is wired like two diodes back to back) in the Precision Power model.
L1, C1-C3 and D1/D2 in the Total Power systems model.

Is this correct?

That is just another fancy name on the same function as shown in my 1950 GE Solid state handbook.
Using bridge rectifier to feed the cap.
Google "surge voltage clamping using capacitor and bridge rectifier"

yah know we didn't used to need stuff like this with vacuum tubes, then again power was more stable back then

Thanks a lot goontron. now I need to hope the coffee I spewed into the laptop doesn't fry the caps.

well i have a point there.
and its the solid state stuff and the HDD that you got to worry about.
