Transfer Function Model of a Brushless Exciter
Journal of King Saud University - Engineering Sciences, 1997 Brushless exciters are widely used in power stations to furnish the excitation current for the main alternators. These exciters are maintenance free and possess high gain and forcing margin. Transfer function models available for such exciters are somewhat complicated and deal with few variables.
