The bondgraphic linear transformer element
Extends from Interfaces.TwoPort (Partial model invoking two bondgraphic connectors).
Information
The bondgraphic linear transformer is a directed TwoPort element. It inherits the effort and flow variables from the directed TwoPort. The transformation constant is modeled as a parameter.The bond graph literature is not consistent in the definition of the transformation constant. In this library, the constant is defined as the amplification of flow from the inflow to the outflow. Some other bond graph references define the transformation constant as the amplification of effort from the inflow to the outflow.
The transformer model has one causality stroke.
Potential variables: e1: Bondgraphic effort variable of inflow f1: Bondgraphic flow variable of inflow, normalized positive for flows into the model e2: Bondgraphic effort variable of outflow f2: Bondgraphic flow variable of outflow, normalized positive for flows out of the model Parameters: m: Transformation constant (default value = 1)
Equations:
f2 = m*f1
e1 = m*e2
