摘要
针对目前发电机并网培训的需要,采用意法半导体(ST)公司生产的32位低功耗单片机STM32F103和DDS芯片AD9832设计正弦信号发生电路,与上位机和同期表一起构成发电机并网模拟系统。首先根据同期表的使用方法,提出系统总体设计方案。然后详细描述AD9832的工作原理和以AD9832为核心的正弦波发生电路,给出了系统的主程序流程图。使用结果表明,该系统具有性能稳定、操作简单等特点。
Aimed at the present demands of training in grid connection of generator, sine wave generating circuit is designed based on DDS chip AD9832 using 32-bit low-power single chip microcomputer STM32F103 as the controller, which makes up the grid connection simulation system of generator combined with upper computer and synchronoscope. Firstly, overall system design is proposed according to the usage of the synchronoscope. Then, basic principle of AD9832 and the design of the sine wave generating circuit with the AD9832 as the core is described in detail, and flow chart of the system main software is given too. The results indicate that the system has stable performance and is easy to be operated.
