Abstract: Rotating rectifiers provide excitation for synchronous generators, and their reliability is very important. A fault monitoring system was designed based on field programmable gate array (FPGA) platform and applied to the online fault monitoring of synchronous generator rotating rectifier. The experiment used a three-stage synchronous generator for online verification. The results showed that the design has a good fault diagnosis effect.
