摘要
提出了一种在数字信号处理器TMS320F2812上生成正弦脉冲宽度调制(SPWM)波的方法,为实现逆变电源的全数字控制提供了有效途径。对SPWM波形生成原理和软件设计方法进行了分析,提出了相应的方案,并且对其进行了实验验证。实验结果可以满足实际需要,在逆变电源中得到广泛的应用。
A scheme of producing sinusoidal pulse width modulation （SPWM） based on DSP was proposed to provide an effective method for digital control in power inverter. This paper analyzed the principle of producing SPWM and the method of software design particularly, presenting relevant strategies, which was tested by experiments. The experimental results show that the proposed scheme can work well and be widely applied to inverse transforming power supply.
