针对电力电子领域的需求，采用自然采样法设计了一个全数字三相SPWM信号产生系统IP软核．通过数字频率合成技术实现了对电源频率的辅确控制．使电源频率精度达到16位．其中。通过调节控制参数．分别实现了电源频率与载波频率的7级、8级控制．最后。搭建了基于FPGA的测试系统．验证了系统功能的正确性．(According to the requirement of power electronics, the natural sampling method for the design of a full digital three-phase SPWM signal generation system. The power frequency of IP core is the auxiliary control is implemented through digital frequency synthesis technology. The power frequency accuracy of 16. By adjusting the control parameters, 7 and 8 levels of power frequency and carrier frequency are realized respectively. Finally, the control of the power frequency and carrier frequency is realized. A test system based on FPGA is built, which verifies the correctness of the system function)
