initial values for semiconductors and switches #1903

Closed modelica-trac-importer closed 7 years ago

Reported by ahaumer on 8 Feb 2016 11:27 UTC When checking Modelica.Electrical.Machines.Examples.SynchronousInductionMachines.SMEE_LoadDump for fixed initial conditions, I realized that the switches with arc (Modelica.Electrical.Analog.Ideal.{OpenerWithArc, CloserWithArc, ControlledOpenerWithArc, ControlledCloserWithArc}, as well as the ideal switches Modelica.Electrical.Analog.Ideal.{IdealOpeningSwitch, IdealClosingSwitch, ControlledIdealOpeningSwitch, ControlledIdealClosingSwitch} are implemented sligthly different and not all offer the possibility to set the initial conditions with fixed=true (for Boolan variable off). I suggest to implement 2 partial models Modelica.Electrical.Analog.Interfaces.{IdealSwitch, IdealSwitchWithArc} and extend the above mentioned switch models from these two partial models. Additionally it would be a great advantage for maintenance to implement a partial model Modelica.Electrical.Analog.Interfaces.IdealSemiconductor and extend Modelica.Electrical.Analog.Ideal.{IdealDiode, IdealThyristor, IdealGTOThyristor} from that partial model. These changes ar backwards compatible, and would be an improvement already for MSL 3.2.2 (possitiblity to set the initial conditions consistently, much easier maintenance).
