FIELD: electricity. ^ SUBSTANCE: all power windings of electric machines are activated mainly in series through rectifiers - disjunctors and in turn with the specified phase delay, and deactivated in turn with the same phase delay, but in reverse order. As a result, output symmetrical voltage of stepped shape, which repeats the contour of sine-shaped signal, is shaped in each half-period. Phase-frequency parameters and amplitude of that signal are specified with control static generator. Non-uniformity and linearity of output voltage curve is provided with up converter circuit of constant voltage levels, which is connected to operation at intervals of activation-deactivation phases of rectifiers - disjunctors, which determines relatively low power fraction generated with high-frequency circuit of up voltage converter in common flow of output power of the plant, and hence the improved reliability at relative low cost of conversion assembly in comparison to inverter circuits of complete voltage conversion. ^ EFFECT: improving the quality of output voltage, and at the same time, the possibility of power buildup of generator plant due to mechanical aggregation of several power electrical machines operating from common drive motor or from several motors. ^ 2 cl, 3 dwg |
