| Abstract: | A theoretical study of the characteristics of current-linear-arnplifier of excitation systepm in brushless AC genertitor is presented.A digital simulation of the exciter with diode-bridge-rectlfier load is done, and an experimental verification is also made.The results show that the realization of these characteristics is probable by choosing reasonable exciter parame-ters at vari-sqpeed.It wili contribute to the reduction of exciting current range of AC exciter,and to the improvement of performance of voltage regulation system of brushless AC genera-tor. |
