METHOD OF POWER SUPPLY LOAD BY DIRECT CURRENT IN SELF-CONTAINED SYSTEM OF POWER SUPLLY OF SPACE VEHICLE Russian patent published in 2018 - IPC H02J7/34 

FIELD: electricity.

SUBSTANCE: according to the method of power supply load by direct current in self-contained power supply system of space vehicle containing a solar battery, connected to the load, from "n" single loads connected in parallel through a stabilized voltage converter and an output filter, storage batteries connected through the discharge converters to the input of output filter, discharge converters, power circuits between the output of the output filter and single loads are projected with resistances based on the relation: ρ⋅l j/In≥R≥Uv / Isc.max., where Uv is the voltage at the output of the self-contained power supply system, V; In is rated current of a single load, A; ρ - resistivity, Om mm²⋅/m; l is the length of power circuit between the output of the output filter and the unit load, m; j is selected current density, A/mm²; Isc.max is the permissible maximum short-time short-circuit current in the single-load circuit, A. In addition, the output filters of the self-contained power supply system are calculated taking into account the permissible short-time short-circuit current.

EFFECT: increasing the reliability of space vehicle operation by limiting the magnitude of a short-term reduction in the output voltage of the power supply system in the event of failure of elements in a hot standby.
