摘　　要：设计了一种新型的基于STM32H743微处理器的发电机励磁调节器,相比于传统的模拟式励磁调节器,其硬件结构简单、性能先进、成本低。利用片内的定时器及设计的外围测频电路,实现了同步信号检测和频率测量功能;利用片内A/D转换接口及设计的外围采样电路和脉冲触发电路实现了A/D采样以及移相触发等功能。给出了励磁调节器的硬件结构框图、软件流程图以及部分功能的原理说明。动模试验表明,基于STM32H743的发电机励磁调节器能够稳定工作,可被应用于实验教学当中。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.
