An Amplidyne is a rotating amplifier. It is a prime‐mover‐driven d.c. generator whose output power can be controlled by a small field power input. An amplidyne is capable of giving a controlled power output in the range of a few hundred to few thousand watts with a power amplification of the order of 10,000 or more and hence finds wide application in feedback control system.
Study of amplidyne whose output power can be controlled by a small field power input. For studying the characteristics.
(i) We plot a graph of Output voltage against effective field current with no load, full load (500W), and without compensation winding effect
(ii) We draw the schematic diagram of an amplidyne system
