Question

Quizplus · Accepted Answer

The commutator of a conventional exciter is replaced with a solid-state rectifier in a brushless DC exciter. A solid-state rectifier is used to replace the commutator in a brushless DC exciter. This allows for more efficient and reliable operation compared to a conventional direct-connected exciter.

In the Brushless DC Exciter, the Commutator of a Conventional
