摘要
针对三相逆变系统,介绍了采用TMS320LF2407芯片,通过混合查表法产生三相SPWM正弦电压的方法,并给出了部分程序源代码,实验结果可以满足实际需要.
For the three phase SPWM inverter system, a new method to generate the three phase SPWM sinusoidal wave is proposed, in which a TMS320LF 2407 chip is employed and a table checking and interpolation method is used. Some of the source codes are given. Experimental results show that it can satisfy the needs of actual application.
