Abstract :
The power converter control system has a great impact on the behavior of the high-speed permanent magnet generator system (HSPGS) due to the high operating frequency. In this paper, a 3-D modeling based on finite-element analysis directly coupled with a power converter control system is built in order to accurately evaluate generator performance. The influence of the control system current time harmonics on the 3-D flux distribution, the vector eddy current in rotor sleeve, and the iron loss of the machine are investigated. The analytical model is validated by experimental test results from a developed prototype of the HSPGS. The obtained results could provide a reference for the system-level design and investigation for the HSPGS in the further design.
