单极性倍频SPWM调制程序,希望对大家有用(Unipolar SPWM modulation frequency doubling process, we hope to be useful)

毕业论文，针对晶闸管三相全控桥式整流电路的主拓扑和调节器进行了设计，主拓扑滤波电路采用了L型滤波器。设计了基于电流模式的双闭环控制系统，并采用工程设计法实现了两个调节器参数的设计，并给出了电流调节器和电压调节器详细的设计过程。(The design of full-bridge control rectifier circuit and controller were studied .The output voltage ripple was inhibited by the L-Filter. )

说明：  ST7920带中文字库液晶原码程序 12864 keil的，串行方式 编写时已经考虑到往avr上的移植了，spi可以用avr硬件的，也可以用io模拟，甚至可以用mega48的串口做spi主机 ，经过我的测试串行方式，在cs无效时，7920还是可以接受数据，导致显示被误改，如果spi上接了其它器件，小心使用。(Driver with the original Chinese font LCD procedure code 12864 Keil. Serial way has been prepared to take into account the transplant avr, 20 avr hardware can be used, io can also use the simulation, or can even be done Serial mega48 20 mainframe, I have serial testing, cs in vain, 7920 can still receive data, resulting in the misuse of reform shows that if 20 on to other devices, careless use.)
