modelDCDCConverter
DC DC converter
Extends from Buildings.Electrical.Interfaces.PartialConversion (Model representing a generic two port system for conversion).
Information
This is a DC/DC converter, based on a power balance between the two DC sides.
The parameter conversionFactor defines the ratio between the two averaged DC voltages.
The loss of the converter is proportional to the power transmitted at the second DC side.
The parameter eta is the efficiency of the transfer.
The loss is computed as
Ploss = (1-η) PDC,
where PDC is the power transmitted. This model is symmetric and the power can be transmitted in both directions. The loss is computed depending on the direction of the power flow.

Revisions
-
March 19, 2015, by Michael Wetter:
Removed redeclaration of phase system inTerminal_nandTerminal_pas it is already declared to the be the same phase system, and it is not declared to be replaceable. This avoids a translation error in OpenModelica. -
June 2, 2014, by Marco Bonvini:
Revised model and documentation. Changed parameter sof the model, now the user specifyVHighandVLowinstead ofconversionFactor. -
January 28, 2012, by Thierry S. Nouidui:
First implementation.
