Extracting best reliable scheme for Electrical Power Subsystem (EPS) of satellite

This paper describes the reliability comparison of different schemes connection for Electrical Power Subsystem (EPS) of satellite. EPS has to be able to provide sufficient power to the satellite subsystems under all possible satellite attitudes. There are eight schemes for EPS, which could be used for power supplying. In these schemes, two main system groups are Peak Power Tracking (PPT) and Direct Energy Transfer (DET) systems. Also in each system, we have four different connections which are Unregulated Bus Using Parallel Batteries, Unregulated Bus Using Linear Charge Current Control Recharge Control, Quasi-Regulated Bus with Constant Current Chargers and Systems Using a Fully Regulated Bus. In this paper we will compare the reliability of different schemes and will introduce the best reliable connection in these two systems for ESP.
