This chapter provides an overview of the fundamentals of all stages of a nanosatellite power system. It looks at power generation from the solar panels, power conditioning architectures to transfer energy from the solar panels to the battery, and power storage in the battery. Photovoltaic solar cells are the most common power source in nanosatellites, although there have been some developments for using other types of primary power sources. Lithium‐ion technology has replaced nickel cadmium technology for most nanosatellite missions. There are two methods commonly used to provide charge to the solar array‐battery: direct energy transfer and maximum power point tracking. The flight switch subsystem provides a method of isolation of the battery and the rest of the electrical power subsystem during storage, transportation, and launch. The chapter also looks at power conditioning topologies for DC/DC conversion and power distribution and protection for effective power delivery to the rest of the satellite.
