【摘要】 介绍了全数字电压型逆变器的三相独立控制技术,解决了其中两个关键问题:一是对称三相给定信号的生成;二是每相逆变器输出电压波形的跟随。实验结果证明了该控制方案能使逆变器在不平衡负载下保持三相输出电压波形的对称性。更多还原

【Abstract】 This paper introduces the three phase independent control strategy for full digital controlled voltage source inverters(VSI).The method for creating three phase sinusoidal reference signals is proposed.Besides,the output control strategy for single phase inverter is also presented.Experimental results prove that the proposed strategy can make the inverter maintaining symmetrical output voltages under unbalanced load.更多还原
