Abstract:

The design of the spacecraft-battery charge-control network was initiated. The network will depend upon the characteristics of the stabistor diode as the basis for its operation. The temperature of the stabistor diode studs will be sensed and compared with the ambient temperature. This temperature difference, converted into a voltage signal will be used to reduce the total battery charging current to a level equal to or less than the safe maximum continuous overcharge rate of the battery. The design of planar stabistor diodes with dice areas equivalent to 120 mil and 180 mil diameter round dice has been started. Materials for the fabrication of such diodes were ordered. A set of specifications for each type of battery needed for the program was drawn up.
