A high initial response excitation system retaining the advantages of the absence of commutators, collectors and brushes while responding with the speed of an electronic exciter has been developed. Calculated performance of this system has been confirmed by factory tests. With the exciter loaded, the excitation system achieved 95 percent of ceiling voltage in 0.016 seconds following a 10 percent step change in the voltage regulator sensing signal. In addition to the high initial response capability, the excitation system also includes supplementary feedback control for improving the small signal dynamic performance characteristic of the exciter. With the addition of feedback, the effective exciter time constant is reduced by a factor of thirty compared to its value without feedback. The tests confirm that low time constants and high initial response can readily be attained in an excitation system which includes a brushless exciter with non-controlled rectifiers.
