DSP实现SPWM波发生的软件开发与应用

Development of application of software for generation of SPWM by DSP

摘要: 介绍了采用TMS320LF2407芯片、通过查表和实时计算两种方法发生SPWM波,并给出了部分程序源代码.比较了两个方法实现SPWM波发生的优缺点,并分析了每种方法的应用范围.

Abstract: It is introduced that a method which can generates SPWM waveform signal by lookup-table and interpolation and real-time calculation, on the basis of TMS320LF-2407 chip. Some of the source codes are given and the two means are also compared in their different application fields.
