DESIGN AND IMPLEMENTATION OF EPS (ELECTRICAL POWER SYSTEM) OF A CUBESAT

This project is to design and implement an EPS for the KN-SAT1. The KN-SAT1 is a Cubesat that has been developed in the University of Khartoum as the first educational Cubesat in the Sudan. The design must provide a reliable power source by satisfying the requirements of charging the batteries with power from the solar cells, regulating the battery voltage to the requested bus voltage and protecting the Cubesat subsystems from the overcurrent associated with the device failure.Cubesats are picosatellites of standardized dimensions which can be operated from universites or radio amateur ground stations. They offer hands-on experience to engineering students in designing, developing, testing and operating a real spacecraft system and its ground segment. One of the most critical aspects of the Cubesat is the Electrical Power System (EPS) since the electrical power is necessary for a Cubesat to operate. The EPS of the Cubesat consists mainly of solar cells, batteries, voltage converters and protection circuits. The EPS is responsible of providing stable power to the Cubesat subsystems.
