Electromagnetic processes are investigated in two versions of a three-phase bridge converter with improved energy characteristics, one of which contains one switching link, and the other two. The commutating link consists of a three-phase capacitor battery and a three-phase group of fully controlled devices. This technical solution makes it possible to ensure the recharging of the capacitors of the commutating link and the control of the energy process of the converter. The main content of the study is the analysis of electromagnetic processes in terms of the features of commutating processes and the proof of the energy capabilities of the options for implementing the converter. The amount of scientific research required for this is divided into three options. Each takes into account the peculiarities of electromagnetic processes associated with different modes of operation of converters, at different frequencies of control pulses of transistors of a commutating link and a shift in the moment of switching on transistors relative to the interval of operation of power electric diodes. As a result, a generalized mathematical model was created. She describes a variety of electromagnetic processes in converters, allows you to calculate the commutating and adjustment angles. They are the main characteristics of the energy process and prove that the developed versions of the converter are compensation. They are able not only to compensate for their own reactive energy, but also, if necessary, to generate reactive energy to the grid. References 12, figures 2, table 1.
