摘要
A circuit, system, and method for a multi-phase bidirectional DC/DC power converter includes a plurality of single phase DC/DC power converter circuits coupled in electrical parallel. A converter controller includes a compensator and a saturation limit function module. The compensator is configured to generate a control signal based on a current command signal and an actual current signal. The saturation limit function module is configured to determine a saturation limit for the compensator while the compensator is in a disabled state. The converter controller is configured to disable one or more of the plurality of power converter circuits, match the saturation limit values of the compensator to current operating values when one or more of the plurality of single phase DC/DC power converter circuits is disabled, and re-enable the one or more of the plurality of power converter circuits using the matched saturation limit values to limit transient current stress as any disabled phases and compensators are re-enabled.
