Method of dynamic parameters for mathematical modelling of switching processes of valves closing of semiconductor converters
A method has been developed for mathematical modeling of valve frequency converters (VFC) based on an analysis of the nature of the occurrence and patterns of the flow of inverse current of valves when they are locked using the dynamic parameters of valves, which are series-connected inductance and...

| description | A method has been developed for mathematical modeling of valve frequency converters (VFC) based on an analysis of the nature of the occurrence and patterns of the flow of inverse current of valves when they are locked using the dynamic parameters of valves, which are series-connected inductance and active resistance, changing in accordance with the pattern of concentration dynamics charges in semiconductor structures (bases, emitters and p-n junctions. Taking into account the presence of the inverse current of semiconductor valves significantly increases the level of adequacy of mathematical modeling of VFCs of arbitrary structure and purpose and in arbitrary modes of their operation, including asymmetric and emergency transient electromagnetic processes of electrotechnical complexes with VFCs, not only during the time interval of switching (closing) of valves, but throughout the entire time modeling.
