THREE-PHASE INVERTER, CONSISTING OF TWO SINGLE-PHASE Russian patent published in 2018 - IPC H02M7/42 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the field of electrical equipment and can be used in power supply systems of facilities, which consumers impose increased requirements to the voltage quality. Inverter contains power terminals, two-phase inverter comprising the first single-phase cell and the phase-shifting device, providing the shift in time between the named cells voltages by angle π/2, output transformer comprising the primary two-phase winding and the secondary three-phase winding and the load connection terminals, at that, the output transformer is made by the locked rotor AC electric machine type, comprising the cylindrical shaped inner core with grooves disposed along its outer surface, in which the primary two-phase winding is located, wherein its phase turns are shifted in space relative to each other by angle of π/2 and coaxial to it outer core in the form of hollow cylinder with grooves disposed along its inner surface, in which the secondary three-phase winding is located, at that, the conductors linear density distribution method along the cores boring is made triangular, wherein the primary winding first phase winding is connected to the first single-phase inverter cell and the second phase winding is connected to the second single-phase inverter cell.

EFFECT: technical result consists in increase in the output voltage quality.
