Answer Posted / saroj kanta nayak
DC Exciation is mostly used, Because We need a constand
magnetic field for ouy power generation. So DC Voltage or a
Natural Magnet can Solve this problem. As using a natural
magnet will be bulky,So insted we use DC windings with
inverter power which draws power from the same Generator
during generation.
