Thats what I thought - and charging at 50amp (on rare occasions) max into 1000 amp-hrs means the ripple per cell is already so low as to not be easily measured.
Mind you, providing a large cap between the rectifier and the battery bank is not likely to be very effective seeing the internal resistance of the bank is so low that to get a suitable time constant would require kilo-farads !!
The ripple is already low. ("so low as to not be easily measured")
The 'R' in RC is the wire run.
Only need to smooth out the ripple voltage a bit.
Not sure of the L in the coils. Been way too long since...
All combined, might almost think of it as RLC low pass filter?
It is one of those things I can't get from my head to the keyboard.
I tested it several years ago.
Small 3-ph iron core PMA but
only used ONE phase.
1000uF? 1500uF? cap on the rectifier at the PMA.
Long run of wire to the battery.
Cap increased the output at the same RPM by 7% if I recall correctly, which is what I expected.
I still believe it is the change from "rectified unfiltered single phase", the ripple current in the resistance of the wire, and the i^2*R wire loss when the wave is in a higher amplitude portion of the current flowing.
The cap smoothed out the current flow (
less ripple current), which reduced the average wire loss.
At least thats the best I can explain whats in my head.
I couldn't make Flux understand it either.
I just know the charging current increased, like I expected it would.
