Power Supply Systems (PSS) serve to provide required-quality uninterruptible power supply to satellite onboard equipment.
Main principle of PSS operation is generation, storage, conditioning and transmission of electrical power to the satellite
instrumentation. A typical PSS includes an electrical generator, i.e. a solar array, storage modules consisting of batteries
with service automatics, and control, regulation, monitoring instrumentation.
- Uninterruptible power supply;
