AC AC converter single phase systems

Extends from AixLib.Electrical.Icons.RefAngleConversion, AixLib.Electrical.Interfaces.PartialConversion.

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 as

V₂ = conversionFactor V₁

where V₁ and V₂ are the RMS voltages at the primary and secondary sides of the transformer, i.e., the 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

P_loss = (1-η) P_tr,

where P_tr is the power transmitted. The model is bi-directional and the power can flow from the primary to the secondary side and vice-versa. Furthermore, reactive power on both side are set to zero.

Note:

This model is derived from Modelica.Electrical.QuasiStatic.SinglePhase.Utilities.IdealACDCConverter.
