Abstract
A power converter (10) functions as a voltage controlled current source with bilateral current capability. When a control voltage is above a prescribed potential, the output current is positive (flowing to a Source Bus (11)), and when the control voltage is below the prescribed potential the output current is negative (flowing from the Source Bus). An additional feature of the controller is an inherent ability to limit a maximum current in either direction. In operation, the power converter functions to regulate a current flowing to the Source Bus from a Battery Bus (13) to satisfy the existing load requirements and, also, functions to charge batteries at a predetermined charge limit, as set by a CURRENT REFERENCE signal, for current flowing from the Source Bus to the Battery Bus.
