ALTERNATING CURRENT AND THE AIRPLANE
ALTERNATING CURRENT AND THE AIRPLANEYou might be wondering, why use alternating current to power aircraft electrical systems? Simply stated, ac power is much more flexible than dc power. Alternating current is produced by all aircraft generators and alternators. This power must be converted to dc if such power is desired. Since converting ac to dc does require some power itself, it only makes sense to convert as little as possible and use mainly ac electrical systems.There are three principal advantages in the use of alternating current for electric power systems. (1) The voltage of ac power can be changed easily by means of transformers. This makes it possible to transmit power at a high voltage with low current, thus reducing the size and weight of …
