UNINTERRUPTED POWER SUPPLY SOURCE Russian patent published in 2010 - IPC H02J9/06 

FIELD: electricity.

SUBSTANCE: source of supply is designed to provide for stable uninterrupted supply of important equipment from two or more independent sources, for increased reliability of supply due to redundancy of channels (in case of supply from single source). Source of uninterrupted power supply comprises main and redundant power supply channel, high-frequency transformer with several primary and one secondary winding, inlet circuits corresponding to separate independent supply channels and connected to primary windings of transformer, outlet circuit common for all supply channels and connected to secondary winding of transformer. Control of priority and selection of channels is based on feedback circuits available in source.

EFFECT: possibility to reject external control and monitoring circuits and to simplify device design, to reduce its dimensions and cost.
