Performance of flux switching integrated starter-generator system with dual-mode control circuit

摘要

Flux Switching Integrated Starter-Generator (FSISG) system was employed to solve the global environmental problems and energy issues. The output performance is vital to the application of FSISG system in Hybrid Electric Vehicle (HEV). In order to investigate the performance of FSISG system, a design methodology of FSISG, a dual-mode control circuit and the relevant control methods were discussed and studied in this paper. Then the experimental investigations were carried out based on the drivers which were manufactured according to the designed dual-mode control circuit. The results demonstrate the excellent performance of FSISG system with dual-mode control circuit. In generating mode, the output voltages of FSISG show a high precision and a well stability in wide rotational speed range. In starting mode, FSISG system shows a well dynamic performance under the different load conditions and load variation condition.
