modelTriode

van der Pol model of vaccum electron tube

Extends from Modelica.Electrical.Analog.Interfaces.OnePort (Component with two electrical pins p and n and current i from p to n).

Information

This is a simple approximation for the nonlinear resistance of a triode.

Note:

If current i is prescribed, voltage v can be unambiguously determined.
If voltage v is prescribed, in the range between the zero crossings the current i has 2 or 3 possible solutions.
