摘　　要：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.The traditional controller based on the single DSP is designed for three-phase system, so it can＇t satisfy the multiphase system. Aiming at the solution, the paper gives a solution programme based on DSP and FPGA. With the feature of FPGA that logic resource is abundant and the programming is flexible, the function units are given such as the encode circuit, PWM generation, the serial port communication, watchdog protection and the latch of states. It expand the system function, meanwhile, it lower the load of the processor and improve the performance. Through the timing simulation and the experiment on the 8MW convertor, the functionality and the reliability of system is validated.
