摘　　要：对无刷同步发电机励磁系统原理进行了分析 ,提出了一种新的高初始响应且能逆变灭磁的励磁系统 .采用了光电系统和高速开关器件 .文中给出了详细的电路 ,并对原励磁系统和新型励磁系统进行了比较实验 。The theory of the brushless excitation system of the synchronous generator was analyzed to develop a new brushless excitation system which possesses high speed response and can invert itself to deexcitate. The design uses poto-electrical system and high speed switches.Detailed circuit,analysis and test results are given. The results prove that the new brushless exication can promote response velocity and improve the stability of the power system.
