FIELD: electrical engineering.
SUBSTANCE: ensured in the proposed AC voltage converter is automatic power supply switching from accidentally de-energised mains to operational mains, ensuring improved reliability of power supply with highly stable AC voltage with the required frequency for critical consumers for whom power supply interruptions are unallowable or highly undesirable.
EFFECT: improved reliability of power supply with highly stable 230 V AC voltage with frequency equal to 400 Hz for different facility consumers receiving primary power supply from 3-50 Hz, 380 V mains.
