摘要:

提出了一种新型空间电压矢量脉宽调制(SVPWM)方法.首先给出了该方法的理论推导、证明和Matlab中的仿真结果,然后对比了新型SVPWM与传统算法2种方法在数字信号处理器TMS320LF2407中的实现方法与算法执行时间.研究表明,新方法具有计算简单、中间直流电压利用率高、开关频率可以优化等特点,有较好的应用前景.

Abstract:

The paper first presents a new space vector pulse width modulation method(SVPWM),and then the deduction,verification and simulation based on the software of Matlab.The novel SVPWM and the classical SVPWM were implemented in the digital signal processor(DSP) of TMS320LF2407,and the execution time of two programs were compared.Simulation and experiment results show that the new method features easy computation and higher utilization of the DC-link voltage,and optimizable switching frequency,so it promises wide application in future.
