Abstract
Voltage is dropped across the variable reistance of a gas responsive sensor to obtain a control voltage which is compared to a ramp waveform reference to cause the comparator to apply pulses to an SCR which supplies corresponding charging pulses to the battery. Another embodiment uses the sensor resistance variation to decrease the current on the base of a transistor which controls the current supplied to the battery.
