An automatic voltage Manage unit controls the sphere latest to maintain output voltage continual. In case the output voltage from the stationary armature coils drops as a consequence of an increase in demand from customers, extra recent is fed to the rotating subject coils in the voltage regulator (VR).

Alternating recent producing devices had been recognised in straightforward forms from the discovery of the magnetic induction of electrical current while in the 1830s.
