Study on the control circuits of Flux Switching Integrated Starter and Generator for HEV application

In order to solve the global environmental and energy problems, Flux Switching Integrated Starter and Generator (FSISG) was applied to Hybrid Electric Vehicle (HEV) application. The control circuits are vital for the FSISG system, which were designed and studied in this paper. The structure of the control circuits of FSISG system was introduced. Then the experimental studies were carried out based on the drivers which were made according to the designed control circuits. 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.
