Modeling current-mode-controlled three-phase converters for simulating multiple-module inter-connected power supply systems

This paper extends the efforts on behaviorally modeling dc-dc power stages to modeling three-phase converters. By equating both the Y- and delta-connection of three-phase sources/loads to a new connection mode, which is suitable for calculating the generated/consumed power, this paper proposes the power transfer model respectively for three-phase boost rectifiers and three-phase voltage source inverters (VSI). The consistency between the proposed models and those previously published for dc-dc converters is discussed. The proposed models can find their applications in simulating multiple-module interconnected power supply systems.
