| Abstract: | 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. |
