exciter is giving dc source to the stator field windings
in case of generators
if we give dc source what will happen is create constant
magnetic field around electromagnets
so whenever rotating conductor cuts the magnetic field the
emf will be induced ,this emf have collected conductor bars
so power is produced
exciter main function is maintaining constant dc source
Excitor produces AC suply which is converted into DC by means of retifier or simply diode bridge.This DC is provided to rotor magnetic field winding producing stong field because DC peak value is high and it is constant.Thus induces Current in the stator armature conductors.In this way,exciter excites the
the main function of exciter of alternator is operate the
alternator and give alternating supply from the D.C source
and to maintain constant terminal voltage by controlling the
under overexcited the machine supplies lagging reactive
power and in under excited it consumes the reactive power
