Shmaliy S. Macromodelling of electric energy semiconductor converters devices

The thesis is devoted to the questions of improving effectiveness of electric power semiconductor converter devices. The feature of descending/ascending designing is the opportunity of implementation of structural and functional creation in advanced environment automated schematic designing. It has been offered the new way of such creation; methods of descending/ascending designing have been developed and realized. Principles of analog macromodels construction for power elements and control system devices of the semiconductor converters, which are intended for hierarchical designing with multilevel modelling by uniform software, are considered. The developed macromodels and new methods of the analysis allow to reduce expenses of time at modelling. Flexible procedure of transition from one kind of model to another allows to combine profundity of the analysis with its comprehensiveness and choose alternately exactness or quickness of modelling as required. The basic results of work have found applicationat designing in Scientific Research Institute of power electronics "Preobrazovatel", factory "Preobrazovatel", and have been introduced into educational process on faculty of electronic systems of ZSEA (Zaporozhye) and on faculty of electronics and automation of DSTU, Dneprodzerzhynsk.
