摘要
介绍了正弦波输出变压变频电源系统。对正弦波输出变压变频电源三种SPWM调制方式及数字化控制策略进行了研究,以期得到一种较理想的调制方式,使变压变频电源的开关管损耗、可靠性及输出电压质量得以改善。并以TMS320F240数字信号处理器为主控芯片,实现逆变电源变频、变压输出,最后给出实验结果。
A VVVF system which outputs sine wave is introduced. Three kinds of SPWM modulation mode and the digital control strategy are studied to get an ideal modulation mode with less power dissipation. higher reliability and better quality of output voltage. Based on the DSP TMS320F240. the experiment was implemented and the result of it was shown in the last to validate the analysis.
