Brushless Self-Excited Three-Phase Synchronous Generator without Exciter.

IEEJ Transactions on Industry Applications, 1992
This paper describes principles together analytic and experimental studies of an exciterless, brushless, and self-excited three-phase synchronous generator which was devised by authors. As traditonal brushless and DC self-excited three-phase synchronous generators without exciter didn't have the self-exciting function by series characteristic component
