Application of integrated circuits in an electronically sequenced battery charger for multiple battery spacecraft

The rapid development of manned and unmanned space vehicles has created a need for larger and more efficent spacecraft power systems.. Accordingly, the problems of battery charging in space have become more difficult to solve as the systems themselves become more and more complex. The initial and relatively simple schemes for diode coupling solar panels and batteries, for example, have given away to sophisticated electronic devices and systems capable of providing a multiplicity of automatic and commandable battery charging modes, adapted to the requirements of a multiple battery spacecraft.
