ABSTRACT:
A three terminal battery equalizer which includes a DC--DC converter has a first filter inductor in the switched, current conducting path connected to the battery ground and a second filter inductor in the switched, current path connected to the non-grounded, non-interconnected terminal of a second battery, and has a capacitor connected between the filter inductors for maintaining the same magnitude of current in the battery equalizer during the time interval when the switching transistors of the DC--DC converter are turned off, as when the transistor switches are turned on. The circuit further includes an error signal feedback circuit for controlling the transistor switches and protective feedback circuits, all providing signals which are integrated to eliminate the effect of alternating voltages, resulting from isolation of the control circuit from the battery circuit. The protective circuits include output current detection for overload protection, reverse polarity protection and temperature compensation.
