The modulated internal effort source is a modulated effort source on its secondary side. The primary side provides the power needed by the effort source. This element can e.g. be used to model a DC power supply together with the power cable that draws the required energy from the grid.
The effort source has its secondary causality stroke away from the source. Its primary causality stroke is free.
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 e0: Effort to be generated (modulated input signal)
Equations:
e2 = e0
e1*f1 = e2*f2
