During operation, the DC converter and a DC battery charger controller in a charger circuit transitions from a first error signal to a second error signal for use in charging a battery, wherein the first error signal and the second error signal, respectively, correspond to feedback sources in a plurality of feedback sources with a plurality of feedback sources. Then, the DC converter and a DC battery charger controller selects a gain and an impedance to ground of a damping circuit based on the selected second error signal, where the damping circuit applies the gain and the impedance to ground to the second error signal. Moreover, the DC converter and a DC battery charger controller selects one or more clamping voltages of a voltage-clamping circuit based on the selected second error signal, where the voltage-clamping circuit applies the one or more clamping voltages to an output from the damping circuit.
