正弦脉宽调制技术(SPWM)在电力电子及工业控制领域有着广泛的应用,特别是在工业与民用中,所以这些领域对SPWM数据的计算精度和速度要求越来越高.以往提出的各种优化算法对处理器或者处理芯片都有较高的要求,同时可能造成资源浪费.在此提出了一种能够节省计算资源的比较算法,动态计算SPWM数据,可以大幅度提高软件计算SP-WM数据的计算速度.%Sinusoidal pulse width modulation (SPWM) is widely used in the fields of power electronics and industrial control. Its application, especially in the industrial and civil fields, has higher requirements of calculation accuracy and speed for SPWM data. A variety of optimization algorithms proposed in the past have high requirements for the processor or processing chip, and may result in waste of resources. A comparison algorithm which can save the computing resources and compute SPWM data dynamically is proposed. It can significantly improve the calculation speed of the data SPWM with software.
