Battery amp Vs phase amp?

[esust]

Thanks all and also thanks to Ferret for summing it up first time i.e 'similar to a buck converter'.

having done some research that makes much more sense, otherwise it seemed like controllers have transformers inside them. seems like the average phase current is higher than the average battery current but peak battery current should be similar to peak phase current.

Cheers for the responses. yes seems like it's acting as a buck converter. that makes sense. Average battery current higher than the average phase current.

I should recommend that explanation:

Hi esust,

You have that backwards. RMS phase currrent is higher than average battery current.

Edit:
You had it right in the other thread.

Note: Average Alternating Current (such as phase current) = zero. So the RMS (Root Mean Squared) value is used.
