modelACACConverter
Extends from Buildings.Electrical.AC.ThreePhasesUnbalanced.Conversion.BaseClasses.PartialConverterYY (Model of a transformer with Y connection primary side and Y connection secondary side).
Information
This is an AC AC converter, based on a power balance between both circuit sides. The parameter conversionFactor defines the ratio between the RMS voltages
V2 = conversionFactor * V1
where V1 and V2 are the RMS voltages at the primary and secondary sides of the transformer (connector N and P respectively).
The loss of the converter is proportional to the power transmitted.
The parameter eta is the efficiency of the transfer.
The loss is computed as
Ploss = (1-η) Ptr
where Ptr is the power transmitted. The model is bi-directional and the power can flow from both the primary to the secondary and vice-versa. Furthermore, reactive power on both side are set to 0.
Configuration:
The image below describes the connection of the windings.
Note:
This model reuses models from Buildings.Electrical.AC.OnePhase.Conversion.ACACConverter.
See Buildings.Electrical.AC.ThreePhasesUnbalanced.Conversion.BaseClasses.PartialConverterYY for details on the connections.
