AUTONOMOUS SYSTEM OF RELIABLE POWER SUPPLY Russian patent published in 2022 - IPC H02J7/34 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering. Autonomous reliable power supply system contains a synchronous generator with a stator, a storage battery, an active voltage rectifier. According to the invention, an additional three-phase winding connected in a star is placed in the grooves of the stator package of the main three-phase stator winding; the beginnings of which are connected to three buffer reactors and three filter capacitors of the active rectifier. The main three-phase winding and the additional three-phase winding have a common magnetic circuit, and the transformation ratio between the main three-phase winding and the additional three-phase winding is selected based on the ratio of the voltage values ​​of the main AC network and the backup DC network.

EFFECT: improvement of mass-dimensional and vibro-acoustic characteristics of an autonomous system of reliable power supply with voltage stabilization of AC and DC networks and galvanic isolation between networks.
