Three-port bridge converter for stand-alone power system

摘要

The article raises the question of the relevance of the use of multiport converters in autonomous power systems. Advantages of this type of converters are given, structure of multiport converter and its control system are reviewed, consider the structure of a three-port converter and automatic control system, explained the algorithm of this system. Also mathematical model that describes converter's modes is shown, ratings of elements and parameters of automatic control system's regulators are estimated. Simulation modelling has been proceeded in order to obtain main waveforms in both static and dynamic mode.
