modelACDCConverter

AC DC converter

Extends from Buildings.Electrical.Interfaces.PartialConversion (Model representing a generic two port system for conversion).

Information

This is an AC/DC converter, based on a power balance between both circuit sides. The parameter conversionFactor defines the ratio between the RMS voltages as

V_DC = conversionFactor V_AC,

where V_DC is the voltage of the DC circuit and V_AC is the RMS voltage at the primary side of the transformer.

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 both the primary to the secondary side and vice-versa. Furthermore, reactive power on both side are set to 0.

Note:

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