Self-excitation characteristics of a hybrid excitation single-phase synchronous generator
2008 18th International Conference on Electrical Machines, 2008This paper describes the self-excitation characteristics of a hybrid excitation single-phase synchronous generator with the features of both wound-rotor and PM synchronous machines. The wound field provides field regulation and allows the field-strengthening operation.

Design and analysis of a novel Hybrid Excitation Synchronous Generator
2008 3rd IEEE Conference on Industrial Electronics and Applications, 2008A Hybrid Excitation Synchronous Generator (HESG) with a simpler configuration is described in detail. The Finite Element Method is used for the calculation and analysis on unload excitation field. An experiment for output voltage control is turned out to be coincident well with those of FEM.

Hybrid excitation synchronous generators for small hydropower plants
2016 XXII International Conference on Electrical Machines (ICEM), 2016Modern rare-earth permanent magnets (PMs) can substantially improve the output characteristics of electrical machines. However, at the same time, the main flux created by PMs is not adjustable, and therefore, permanent magnet synchronous generators (PMSGs) are inappropriate for some applications where the reactive power regulation is required.

Nonlinear H-infinity control for hybrid excited synchronous generators
2020 IEEE 14th International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG), 2020The model of a hybrid excited synchronous generator is analyzed and a nonlinear optimal (H-infinity) control method is proposed for it. This type of generator receives primary excitation at its stator’s winding through an AC/DC and DC/AC converter, and auxiliary excitation at a secondary winding that is fed by an AC to DC converter.
