Terminal Voltage Oriented Control of Excitation Winding for New AC-Excited Hybrid Excitation Generator

2021 24th International Conference on Electrical Machines and Systems (ICEMS), 2021
Hybrid excitation synchronous generator(HESG) inherits the high power density and high efficiency of permanent magnet synchronous machine(PMSM), and solves the problem that the air gap magnetic field of PM machine is difficult to adjust.

A Two-Stage Brushless Excitation Method for Hybrid Excitation Synchronous Generator

IEEE Transactions on Magnetics, 2015
A two-stage brushless excitation method for hybrid excitation synchronous generators (HESGs) is proposed in this paper. Comparing with the traditional three-stage brushless excitation method, the auxiliary exciter is eliminated. The complete self-excitation is realized. As the main generator of two-stage brushless generation system, a tangential/radial
