Answer / nilkanth tailor

yes....we can use...but for that we need high power IGBT
which can take load 3 phase motor....
i think that for 3phase UPS,we have to make 1phase to 3
phase converter...and suppose thier is no any electricity
thier then high current capacity battery will be needed coz
thier is 3phase so more power u need, this battery suppy is
given to 1 phse and it convert in to 3 phase by
converter...for that we use IGBT....and this 3 phase given
to the 3 phase motor...
