Abstract

The electrical power system EPS of a small satellite provides electrical energy to all the systems onboard and the payload and it is the most critical system of a satellite. The EPS, in general, consists of solar cells, rechargeable batteries, a power conditioning and distribution units.

The solar cells are the primary source of energy. These photovoltaic cells convert light into electrical energy. The batteries provide power during eclipse as well as during peak load times.

The power conditioning and distribution units provide a stable power bus and distribution of power through power switches to all satellite subsystems. The satellite can only operate normally as long as it has power. A failure of the EPS without any doubt will result in the end of the satellite’s mission.

The purpose of this paper is to give a deep insight on how to design circuits for battery and solar panels temperature compensation over a wide range of temperatures (-40°C to +40°C). Both temperature circuits will be based on thermi-linear network of the type YSI 44203. The thermo couple will be located on each of the four solar panels and in the battery pack. Data from these networks will be routed to the BCR for temperature compensation. The design will be based on off the shelf components COTS.
