a solar energy installation utilizes a three phase bridge
converter to feed energy into power system through a
transformer of 400v/400v.the energy is collected in a bank
of 400v battery and is connected to converter through a
large filter choke of resistance 10ohms.1.the maximum
current through the battrey will be.2.the kva rating of the
input transformer is.

a solar energy installation utilizes a three phase bridge converter to feed energy into power syst..

as we have given battery voltage 400v which is dc voltage.
choke resistance is 10ohm which is in series with battery so,
max current through the battery will be=400/10
=10amp
10amp is a dc current max current is = sqrt2*10
kva rating is = kv*i
400*sqrt2*10
=22.6kva
