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.
