Modeling and Experimental Verification of High-Frequency Inductive Brushless Exciter for Electrically Excited Synchronous Machines
Artikel i vetenskaplig tidskrift, 2019

Electrically excited synchronous machines have shown potential to be an alternative to permanent magnet synchronous machines in electromobility and wind power applications. High frequency wireless power transferring technology enables a compact design of brushless exciters for the machine. In this paper, a dynamic model of high frequency brushless exciters is proposed for the purposes of operating condition monitoring and excitation control. The modeling is done by using arithmetic and differential equations, as well as considering different operation modes of the system. The operation modes are defined based on the physical behaviors of the excitation circuit. The model is verified by experiments with variations of different circuit parameters. With the proposed model, further studies, including parameter sensitivity study, component parameter selection and loss analysis are conducted to demonstrate the effectiveness of the model. These studies can be used to assist design and optimization of the brushless excitation system.
