摘要
论述了SPWM原理和对称规则采样法,介绍利用数字信号处理器TMS320F2407产生SPWM波形的方法,该方法具有高效、简洁、实时性强以及硬件电路简单等优点,该方法的特点是采用查表和在线计算相结合,既能满足一定控制精度要求,又能满足实时控制要求。实验结果验证了设计的正确性。
This paper mainly discusses the theory of the SPWM and the sampling method of the symmetry principle,and introduces the method which produces SPWM waveform by a series of DSP-TMS320F2407.Being efficient and succinct,it can also strengthen the real-time character and simplify the design of the hardware circuit.The design meets certain control accuracy and real-time control demands by applying table-consulting and on-line calculation.Experiment result proves the validity of the design.
