Hi Folks
I am sure that somewhere in the not too distant past, I read about a technique whereby connecting a capacitor between the + and - rails (not 0 volts) would cause the two rails to track each other fairly closely.
I can't find the details about the technique and how to choose the value of the cap. Has anyone got any information or knowledge about it
The application is a +/- 40 volt supply at about 4.5 Amps for a Class A amplifier that is housed in a separate chassis from the amp and connected by an umbilical cord.
The configuration is:
Toroidal transformer -> Diode bridge -> bank of 45,000uF initial smoothing caps -> umbilical cord to amp chassis -> bank of 30,00uF reservoir caps -> Cap multiplier -> amp module.
I think that the 'tracking caps could probably go anywhere in the chain, but gut feeling says on the second bank of reservoir caps.
Thanks for any help
Mike
