Object of researches - principles of construction and realization of multilevel converters of frequency of an medium voltage (up to 10kV). The purpose of work. Development of principles of realization and new decisions of construction of multilevel converters of frequency which will provide increase of their power parameters and characteristics at a minimum quantity of elements. Methods of research - the general principles of the theory of modern semi-conductor converters, theoretical bases electrical engineers, mathematical modelling and numerically-analytical methods of calculation on a computer. Existing decisions of converters for maintenance of parameters an input-output up to the standard provide a plenty of elements in power circuits that causes significant losses of energy and cost of the converter. It is established, that the principle of asymmetry of voltage allows to increase quantity of levels of a output voltage by the switch of the inverter; additional simplification of a part of a direct current is reached in hybrid schemes with a jet cell which class it is offered to expand, it is offered to carry out redistribution of loading of inverters for exception of circulation of energy, the opportunity of reduction of quantity of switchings of switchs and corresponding losses of energy is shown. Results of work are used in educational process in rates "Power electronics", "Electric drive". Prognosis assumptions concerning development of object of research - improvement of principles of redistribution of loading in the scheme of the converter with use of a jet cell. Degree of introduction - use of results by development of multilevel converters by the Ukrainian institute of power electronics " Converter ".
