DW8051单片机的设计，用HDL设计，详细的HDL设计-DW8051 microcontroller design, HDL design, detailed design of the HDL

说明：  使用STM32官方提供的DSP库进行FFT，虽然在使用上有些不灵活（因为它是基4的FFT，所以FFT的点数必须是4^n），但其执行效率确实非常高效，看图1所示的FFT运算效率测试数据便可见一斑。该数据来自STM32 DSP库使用文档(. Using the official DSP library provided by STM32 for FFT is not flexible in use (because it is the FFT of base 4, so the number of FFT points must be 4 ^ n), but its execution efficiency is really very efficient, as can be seen from the test data of FFT operation efficiency shown in Figure 1. This data comes from STM32 DSP library usage document)

AD9910实现脉冲内线性调频信号，仅供参考(AD9910 to achieve linear FM pulse signal, for reference only)

针对兆瓦级风电并网逆变器主电路研制中存在的并联扩容、开关频率较低和LCL滤波器难以优化设计等问题，提出了采用交流侧串接电感再进行并联的均流方案，采用载波移相技术提高变流器的等效开关频率，提出了LCL滤波器的设计原则，并给出了上述设计的理论依据和实现方法。通过对2兆瓦风电变流器主电路的仿真验证了上述技术方案。(MW-class wind power for grid-inverter main circuit of the parallel development of existing capacity, a lower switching frequency and LCL filter design difficult to optimize the problem, a series inductor AC side in parallel are further flow program, the use of carrier phase-shifting technology to enhance the equivalent converter switching frequency, a LCL filter design principles, and gives the above-mentioned theoretical basis for the design and implementation. 2 MW of wind power converter main circuit simulation program to verify the above-mentioned technology.)
