| 摘 要： | 在三相逆变器中,出于体积和成本的考虑,滤波电感和输出变压器通常都采用三磁柱结构,但其三相磁路的相互耦合使得三相逆变器的动态分析非常地困难.该文基于瞬时值对称分量变换建立了带三磁柱电感和变压器的三相逆变器数学模型,该模型简单实用,并实现了三相的解耦.该文基于该模型分析了三相逆变器的动态特性,发现逆变桥输出电压的零序分量对三相逆变器的运行有着很大的影响.仿真与实验验证了上述结论.

| Abstract: | In three-phase inverters, the three pole reactors and transformers are normally used for the consideration of the cost and cubage. However, the magnetic coupling between three poles makes the dynamic analysis of three-phase inverters ultra difficult. This paper established the model of three-phase inverters with three pole reactors and transformers based on the instantaneous symmetric component transformation. The model was simple and practical which can realize the decoupling of three phases. The analysis based on this model indicates that the zero sequence voltage output from the inverter bridges has great influence upon the three phase inverters. The simulations and experiments validated the above conclusion. |
