| Abstract: | 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. |
