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.)

我是VHDL的初学者，这是我自己编译的简单的几个VHDL码，功能有3-8解码器及其testbench,16位寄存器及其testbench和交通灯。 希望能和其他初学者一起讨论学习，并得到高手的指点-I VHDL beginners, this is my own translation of a few simple VHDL code. 3-8 function decoder and testbench, 16 Register and testbench and traffic lights. Hopes to be able to discuss other beginners learning, and with the guidance of the master
