A MULTIFUNCTIONAL CONVERTER FOR THE INVESTIGATIONS AND TRAINING IN THE FIELD OF THE ELECTRIC ENERGY CONVERTERS

The converters of the DC-AC or PWM direct-current power are more widely used devices for the automated electric drives control, as well as for the different technological processes control. In principle they are multi-parametric systems, because of the electromagnetic processes in them are due to the interaction of the many factors. The multi-parametrication determines the significant difficulties by analyzing, optimizing and practical research of them, too. From this point of view with the purpose of an intensification of the lecturers’, students’ and graduate students ’ research and development work from particular necessity is the creating a multifunctional converter experimental configuration as a base module for the investigations and training in the field of the electric energy converters. In this paper the results from the electric converter design and research are presented that depending on the switching devices control algorithm can be realized the following functions: a full-bridge transistor inverter for the DC load control; a full-bridge transistor resonant inverter and the PWM inverter. An experimental model for the lecturers’, students ’ and graduate students’ development and training are proposed. 1
