METHOD OF SPACECRAFT POWER SUPPLY Russian patent published in 2017 - IPC H02J7/34 

FIELD: electricity.

SUBSTANCE: according to the method of spacecraft power supply from the solar battery, the solar battery is connected through a rotary device with current collectors to the input positive and negative buses of the stabilized voltage converter, the battery is connected by its positive and negative buses to the input of the discharging and the output of the charging devices is made in the form of a bridge inverter with a transformer with n output windings, where n≥2, and the input of the charging device is connected to one of the output windings of the transformer; to the other (n-1) output windings of the transformer, transient communication devices with loads with their own output voltage ratings are connected. Wherein the solar battery is selected with the maximum initial output current, in terms of the design capabilities of the current collector used in the rotary device of the spacecraft, and the output voltage at the operating point at the end of the resource is selected from the relation: U_SB≥Pl/(I_SB, k_co), where Pl is the maximum load power, taking into account the power for charging the battery, W; U_SB - the output voltage of the solar battery at the operating point at the end of the resource, V; I_SB - the output current of the solar battery at the operating point at the end of the resource, A; k_co - a coefficient taking into account the voltage conversion loss, and the number of photoconverters in one serial circuit of the solar battery is selected based on the relation: n≥U_sb/U_el, where U_el is the voltage of one photoconverter at the operating point at the end of the solar battery resource, V.

EFFECT: improving the specific energy properties and operation reliability of the power supply system of spacecraft.
