传统的DSP 控制通常针对的是三相系统,其外设资源不能满足多相逆变器的控制要求,文中

提出一种DSP + FPGA 的控制器解决方案. 特别利用了FPGA 逻辑资源丰富,编程灵活的特点,设

计了译码电路、脉冲发生、串口通信、看门狗保护、硬件状态锁存等功能单元,在有效扩展系统功能

的同时,降低了运算单元的负荷,提高了整体性能. 对设计进行了时序仿真,并将其应用于8 MW逆变器的控制系统中,结果验证了设计方案的功能性与可靠性.-Traditional DSP control is usually targeted at three-phase system, its peripherals resources can not meet the requirements of multi-phase inverter control, the paper presents a DSP+ FPGA controller solutions, especially the use of the FPGA logic resource-rich, flexible programming characteristics, the design of the decoding circuit, pulse, serial communication, watchdog protection, hardware, latches and other functional unit state, the effective expansion of system functions, while reducing the computing unit load, improve the overall performance of the design for timing simulation, and applied to 8 MW inverter control system, the results validate the design' s functionality and reliability.
