Brushless Thyristor Excitation Systems.
IEEE Transactions on Power Apparatus and Systems, 1972This paper shows how brushless thyristor excitation systems for large synchronous generators are being evolved in the authors' organisation, outlines the electrical and mechanical advantages that accrue, and includes some results of a digital computer comparison of such systems with other forms of excitation.

Analysis of polyphase brushless exciter
Conference Record of the 2000 IEEE Industry Applications Conference. Thirty-Fifth IAS Annual Meeting and World Conference on Industrial Applications of Electrical Energy (Cat. No.00CH37129), 2002This paper presents the modeling and simulation of the operation of an 11-phase brushless exciter. The analytical method is based on Kron's tensor method, which is developed for dealing efficiently with the time-varying topology of an exciter circuit during a digital computer solution.

Flux pump excited brushless alternator
IEEE Transactions on Magnetics, 1981Experimental measurements obtained for a novel brushless superconducting alternator that makes use of a flux pump of the rotating spot type are presented. The flux pump, used to provide the excitation current of the field coils incorporates several features of a machine studied theoretically and reported in an earlier paper.

The brushless excitation system
Electrical Engineering, 1960A NEW TYPE of excitation system has been developed for use in the electric utility industry in which the generator collector and collector brushes, and the exciter commutator and commutator brushes are eliminated. The basic difference between this system and its predecessors is an a-c exciter mounted on the same shaft as the generator field.

Integrated brushless excitation for Hybrid Excitation Synchronous Generator
2015 IEEE Magnetics Conference (INTERMAG), 2015Brushless excitation generator is highly reliable and easily maintained.[1] In this paper, an integrated brushless excitated method (IBEM) is proposed in this paper. It can realize brushless excitation for the generator whose excitation windings are placed on the rotor.

Brushless self‐excited three‐phase synchronous generator without exciter
Electrical Engineering in Japan, 1993AbstractThis paper describes principles together with analytic and experimental studies of an exciterless, brushless, and self‐excited three‐phase synchronous generator which was devised by authors. Since traditional brushless and dc self‐excited three‐phase synchronous generators without exciter did not have the self‐exciting function by series ...

IEE Proceedings - Generation, Transmission and Distribution, 1994
The IEEE model of a brushless exciter can be found in many software packages for the simulation of power system behaviour. Yet the model is simplistic and does not represent the exciter alternator accurately. This paper describes the reasons for the inaccuracy of the IEEE representation and proposes an alternative model.

Synchronous Generator With Embedded Brushless Synchronous Exciter
IEEE Transactions on Energy Conversion, 2019A new brushless and permanent magnet less synchronous generator is reported in this work. Contrary to traditional brushless synchronous generators that use an extra machine along with rotating diode rectifier, the proposed machine houses the main and the exciter machine in the same frame.

Performance of Brushless Induction Excited Synchronous Generator
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2019This paper reports a brushless induction excited synchronous generator. An induction machine (IM) and a synchronous machine (SM) are embedded in the same machine frame. To avoid the magnetic interaction between these two machines, they are configured for different numbers of poles. However, rotor windings of both machines are electrically coupled using

Excitation scheme of brushless self-excited-type three-phase synchronous machine
IEEE Transactions on Industry Applications, 1992AC excitation schemes of a brushless self-excited-type three-phase synchronous machine are presented. The rotor field windings of the machine are short circuited with the diodes, and an exciter or other exciting equipment is not required in this machine.
