INVERTER SYSTEM AND INVERTER SYSTEM CONTROL METHOD Russian patent published in 2022 - IPC H02M7/483 G05F1/565 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, in particular to inverter systems. An inverter system is provided, comprising a level jump prevention control unit 3 that outputs a control signal based on a voltage level command V*; and the control signal controls the inverter 4. The level jump prevention control unit 3 sets the value of the counter C so that if the output voltage level V of a certain phase moves up, the output voltage level V of the phase is prohibited from moving up for a predetermined time, and the other phase the output voltage level V is prevented from moving down for a predetermined time. The level jump prevention control unit 3 also sets the counter value C so that if the output voltage level V of a certain phase moves down, the phase output voltage level V is prohibited from moving down for a predetermined time, and for the other phase, the output voltage level V is prohibited from moving up. within a predetermined time.

EFFECT: suppression of the shift in the level of interphase voltages in an inverter system having an arbitrary number of phases and an arbitrary number of levels.
