This link extends GunnsBasicConductor with the ability to create a constant power dissipation in the conductor. It modulates its internal conductance G according to:

where P is the desired power dissipation and V is the voltage drop across the link. As the voltage drops, the link increases G to maintain the constant P, and so on. The link has a minimum voltage below which it switches off, setting G = 0, mainly to avoid dividing by zero but also for network stability.

This link has the same connection rules as GunnsBasicConductor. The picture below shows how it is typically used:

Port Connection Rules (These are limitations on the port connection to nodes that the link enforces in run-time):

• Same as GunnsBasicConductor.

Other Rules (These are extra rules you should always try to follow):

• Same as GunnsBasicConductor.

Configuration Data Parameters:

• defaultConductivity: Same as GunnsBasicConductor. This link does not use this config term, so you can leave it zero.
• defaultPower (default = 0.0 (W), must be >= 0): This defines the default constant power value that will be dissipated in the link.
• minimumVoltageLimit (default = 0.0 (W), must be >= 0): This defines the minimum voltage across the link (not input voltage). When the actual voltage across the link is below this value, the link switches off by setting its conductance to zero (open-circuit). Note that the output port does not have to connect to the Ground node, thus we distinguish between voltage across the link vs. input voltage.

Input Data Parameters:

• malfBlockageFlag: Same as GunnsBasicConductor.
• malfBlockageValue: Same as GunnsBasicConductor.
