摘要
将正弦脉宽调制(SPWM)控制技术应用于矩阵变换器中,导出了矩阵变换器的SPWM调制策略,控制开关函数不需要复杂的数学推导和计算。利用TMS320F240数字信号处理器设计了矩阵变换器控制系统,分析了该系统的控制方法,给出了系统的硬件框图、软件流程图。该系统可满足矩阵变换器对控制实时性的要求,且性能良好,系统软、硬件设计简单。
In this paper, SPWM control technology is applied to matrix converter. SPWM strategy of matrix converter is deduced. Control switch functions of matrix converter do not need complex mathematics deduction and calculation. The control system of matrix converter is designed by using TMS320F240 DSP. The control methods of the system are analyzed. The block diagram of hardware and the flow chart of software are given. The system not only meets the requirements of real-time control and demonstrates high performance, but also simplifies the software and hardware of the system.
