摘要： A generator transfer function regulator incorporating two control loops. The first control loop produces a first generator excitation control signal (U) which varies to compensate for variations in the magnitude of the generator output voltage (V.sub.1) . The second generator loop produces a second generator excitation control signal (U.sub.e) which varies so as to maintain substantially constant the response of the generator system to variations in the generator output. The two control signals are combined and applied to a conventional generator exciter circuit (2). As a result, the generator terminal voltage (V.sub.1) control performance achieved by the AVR under open circuit conditions is effectively maintained when the generator is loaded over its range of operation, irrespective of the power system which the generator feeds.

摘要： A full-wave-rectifying-circuit is composed of six diodes and six transistors inversely connected in parallel with the diodes. A phase-control-circuit has three magnetic sensors each of which corresponds to one of the phase-windings and positioned so as to lag by an electric angle of 90.degree. to provide digital signals which lag an electric at an angle of 60.degree. behind the induced-phase-signal. The six transistors are driven by the digital signals to form controlled AC voltages which lag behind the induced line voltages by an electric angle 60.degree. so that the alternator increases the output power without increase of the body size.
