Kinetics Control Systems SVRI Exciter/Regulator rectifier is designed and rated in capacity for the application of exciting the DC fields of an AC generator operating independently with other generators and/or NOT tied into a utility power grid. The SVRI rectifier is a packaged system for the application of excitation of an AC generator field from a "black start" condition utilizing residual magnetism, regulating DC to the generator field for stable generator operation and capacity for 150% rated field forcing. The SVRI DC voltage regulation and field forcing capacity permit the SVRI excitation system to compensate for "voltage droop" resulting from step or impulse loading variations. Kinetics’ solid state logic circuitry provides a timed interval unit phaseback circuit preventing the generator field and exciter from operating in the "forced" mode for an excessive period of time.
