#142708 - Filtering or regulation
Responding to: ???'s previous message
M said:
Is there any way (any "practical" method) to decrease the ripple (to make capacitor voltage more constant)?

These are two issues:
You can decrease the ripple by a suited filter, but the average output voltage will still decrease.

A suited filter consists of two big storage caps, connected by a choke (pi-filter). But this choke must be huge to allow a low corner frequency to remove the ripple and to not go into saturation with the high currents.

Another way would be the active regulation, by the help of step-up/down regulator.
