Abstract
A multiple battery source of multiple voltages is connected to the input of a switching regulator in which the currents sourced by inverting and non-inverting inputs are compared for balance, and when the imbalance is generated by external circuitry and 'error' current is detected by the comparator circuit which thereupon provides an electrical output correction signal to the switching circuitry to correct the imbalance.
