| 摘 要： | 针对三相四臂对逆变电源提出了一种新的控制方法,即在对三相输出电压不平衡机理分析的基础上,通过设计负序、零序控制器,消除了三相四臂对逆变电源中负序和零序分量的影响,从而保证三相相电压在不平衡负载下的对称输出,仿真结果验证了该方法的可行性.

| Abstract: | A new control scheme for 3-phase 4-wire inverter power supply is presented. By the analysis of the unbalanced mechanism of the 3-phase output voltages, negative and zero sequence components is the ultimate cause to bringing three phases voltage unbalance. Based on synchronous frame, a negative and zero sequence controller is designed, it can eliminate the effect of negative and zero order for 3-phase 4-wire inverter power supply, it makes the output voltage waveforms symmetrical. |
