Abstract:

Two modes of operation for a stabistor charge control circuit 1 thermal coupling the stabistor to the cell and 2 thermal isolation of the stabistor from the cell are discussed. Thermal coupling was demonstrated in circuits BCC-2 and BCC-3, where the former cycled for 2700 cycles and the latter for 785 cycles. Thermal isolating was demonstrated in circuit BCC-4 which cycled over 400 times. Preliminary investigations indicate that a germanium power transistor may be used more effectively as an antireversal diode than the germanium diode now being used.
