OUTPUT STABILIZER OF BRIDGE THREE-PHASE INVERTER Russian patent published in 2024 - IPC H02M7/42 H02M5/10 G05F3/06 

FIELD: electrical engineering.

SUBSTANCE: invention can be used as an output stabilizer of a bridge three-phase inverter in power supply systems for consumers that have increased requirements for voltage stability and sinusoidality. The output stabilizer contains in each phase a ferroresonant voltage stabilizer, input and output coils, a closed series oscillatory circuit and a capacitor. A closed series oscillatory circuit includes two coils connected in series and in accordance. The output and output coils are connected in a star. In each phase, the input coil, the first coil of the closed series oscillating circuit and the output coil are placed in grooves on the inner side of the outer core of the toroidal shape, and the coil of the ferroresonant voltage stabilizer and the second coil of the closed series oscillating circuit are placed in the grooves located on the outer side of the inner core of the toroidal shape. The outer and inner cores are made solid and toroidal in shape and made from sheets of electrical steel, and placed coaxially. The inner core is installed inside the outer core with an air gap between them.

EFFECT: effective performance.
