Implementation of Power Control and Distribution of a Cube-Satellite
Nowadays, doing the researches in Satellites technologies are prosperous and beneficial for the developing countries. Cubesats are 10 cm side cubic shape satellites which can be perform various missions in space (i.e. imaging the Earth, imaging the Moon, Weather observation, etc.). The main advantages of the Cubesats are the relatively low cost and the short time which are required for development. All over the world, the students of the final years in Engineering Schools try to implement and build the Cubesats or any of its subsystems. The knowledge and experience which can be attained by the students during and after implementation process of such practical projects are very useful before indulging the professional careers. A Cubesat’s Electrical Power Subsystem (EPS) is dedicated for power generation and control, energy storage, and power distribution. The top-level typical functions of EPS can be summarized as: 1. To supply continuous power to the loads during the mission lifetime. 2. Control and distribute electrical power to the satellite. 3. Fulfill the loads average and peak power requirements. 4. Provide regulated voltage bus to the loads. 5. Provide command control capability and telemetry of the subsystem’s health. 6. Protect the spacecraft against any failures within EPS. The generation is dene using high efficiency solar cells which will be mounted on the satellites bodies. The storage is ensured by using rechargeable batteries.
