Information

Diodes are switching elements that are primarily being used in electrical circuits, although nothing prevents them from being used also in other energy domains. Leaking diodes are a special class of non-linear resistors.

The causality of the leaking diode element is free.

Potential variables:

 e:         Bondgraphic effort variable

 f:         Bondgraphic flow variable, normalized positive for flows into the model

 blocking:  Boolean variable denoting the switch position (internal modulation signal)

 s:         Curve parameter


Parameters:

 Ron:       Leakage resistance in conducting state (default value = 1e-5 Ohm)

 Goff:      Leakage conductance in blocking state (default value = 1e-5 Mho)

 e0:        Forward threshold effort (default value = 0 Volt)

Equations:

blocking = s < 0
f = s*(if blocking then Goff else 1) + Goff*e0
e = s*(if blocking then 1 else Ron) + e0
