DIODE CONTROL RESEARCH.
Abstract
A circuit designed to sense the temperature of the stabistor heat sink was tested with a five-cell battery protected by stabistors and charged at C/1. The circuit successfully detected end-of-charge and reduced the charge current to the safe overcharge rate. Tests on different junction area stabistors indicate that the forward voltage tends to vary inversely with area, so that the proper combination of area and number of junctions may permit stabistor charge control of silver-zinc and silver-cadmium cells. Weight and volume studies of theoretical stabistor charge control systems for aircraft batteries charged at 350 and 220 amperes were conducted. Major problems in designing such systems could be low stabistor voltage and high leakage during open circuit stand, both resulting from the large area junctions required. (Author)
