SPACECRAFT POWER SUPPLY SYSTEM Russian patent published in 2019 - IPC H02J7/34 

FIELD: electrical engineering.

SUBSTANCE: power supply system of the spacecraft consists of a solar battery connected by its plus and minus tires to a voltage regulator, made using an inverter bridge circuit, a battery connected to its inputs and minus buses to the inputs of a discharge device built on an inverter bridge circuit, and the output of the charger, the voltage regulator and the discharge device are connected to different matching transformers, the outputs of the voltage regulator are connected to the primary winding of the first power transformer, and the outputs of the discharge device - with the primary winding of the second power transformer, the information outputs of the battery connected to the control device of the state of charge of the battery, the control inputs of the charger and inverters of the voltage regulator of the solar battery and the discharge device of the battery are connected to the outputs of the control device with extreme regulation of the power of the solar battery, the first input thereof is connected to the control output of the battery charge monitoring device. In the power supply system of the spacecraft, the charger is connected to the solar battery by the inputs, the second and third inputs of the control device are connected respectively to the output of the additionally introduced power sensor and to one of the outputs for connecting the load, the output windings of the first and second power transformers through individual rectifiers are connected in parallel to the outputs for connecting the load.

EFFECT: technical result is an increase in energy efficiency, an increase in the functionality of on-board power supply systems (PSS), and an improvement in electromagnetic compatibility.
