Spacecraft Power Systems Using the Flyback Converters

The paper presents harvesting of solar energy by the charge controller techniques to charge the battery bank at a particular voltage during the daylight by the Flyback converter to utilize this power at spacecraft power systems during the orbital night or when the load demand exceeds the solar cell or array ability. All bits and pieces are monitored and controlled by the Flyback power supply unit or converters as light weight, high power density, compact size, least cost, low profile, low volume, tight regulations, good design, high reliability and high efficiency.
