| Abstract: | A new generator excitation regulator based on STM32H743 microprocessor is designed, and compared with the traditional analog excitation regulator, its hardware structure is simple, its performance is advanced and its cost is low. The function of synchronous signal detection and frequency measurement is realized by using the on-chip timer and designed peripheral frequency measurement circuit. The functions of A/D sampling and phase-shifting triggering are realized by using the on-chip A/D conversion interface, peripheral sampling circuit and pulse triggering circuit. The hardware structure block diagram, software flow chart and the principle explanation of some functions of excitation regulator are presented. The dynamic model test shows that the generator excitation regulator based on STM32H743 can work stably and can be applied in experimental teaching. |
