New examples

The following new examples have been added to Modelica.Electrical.Analog.Examples:

CharacteristicThyristors, CharacteristicIdealDiodes, HeatingNPN_OrGate, HeatingMOSInverter, HeatingRectifier, Rectifier, ShowSaturatingInductor ShowVariableResistor

Improved existing components

In the library Modelica.Electrical.Analog.Ideal, a knee voltage has been introduced for the components IdealThyristor, IdealGTOThyristor, IdealDiode in order that the approximation of these ideal elements is improved with not much computational effort.

In the Modelica.SIunits library, the following changes have been made:

Inductance | min=0 removed
SelfInductance | min=0 added
ThermodynamicTemperature | min=0 added
