Hybrid Models of Electric Arc with Improved Dynamic Characteristics in Wide Ranges of Changes in Bipolar Current Value

Antoni Sawicki

The article discusses the limitations of the Mayr and Cassie linear models and of the Mayr generalized model accompanying the precise mapping of electric arc column within a wide range of changes in bipolar current. The research involved the development of new non-linear hybrid models of arc by the association of linear and non-linear models, the creation of arc hybrid macromodels and the verification (utilising the MATLAB-Simulink software programme) of the efficiency of dynamic voltage-current characteristics through simulations of processes in a simple circuit with electric arc.
