METHOD OF LOAD POWER SUPPLY BY DIRECT CURRENT IN SELF-CONTAINED SYSTEM OF POWER SUPPLY OF SPACE VEHICLE Russian patent published in 2015 - IPC B64G1/44 H02J7/34 

FIELD: electricity.

SUBSTANCE: invention relates to electric engineering, namely to self-contained power supply systems of space vehicles using solar panels as initial power sources, and batteries as energy accumulators. The load method of supply by direct current in the self-contained power supply system of space vehicle means that voltage stabilizer, charger and discharge device are controlled depending on input and output voltage of the power supply system. At that using the measuring shunts the load current and charge-discharge current of the batteries are monitored. Besides, output voltage of the power supply system is monitored using the threshold sensors, and intermittent load is disconnected upon achievement of the threshold values of the output voltage. Additionally dynamic of the transient processes is monitored in relation to change of the output voltage and load current with time using the quick-response memory units, that are switched on upon achievement of the threshold values of the output voltage. Re-switching on of the intermittent load is made after results analysis of the memorized dynamic of the transient processes.

EFFECT: increased operation reliability of the space vehicle in case of accidents linked with off-design decreasing or increasing pf the output voltage of the power supply system.
