Abstract
A system and method for controlling cross current in an interleaved power converter system having a plurality of converter threads coupled in parallel includes collecting a feedback current from each thread and obtaining a normal current and a differential mode current for each thread, based on its respective feedback current. The normal current of each thread is regulated to a commanded thread normal current value via a respective normal current control loop based on d-q rotating frame parameters. A differential mode cross current of each thread is regulated to zero via a respective differential mode cross current control loop based on d-q rotating frame parameters; while a differential mode cross current DC offset of each thread is regulated to zero via a respective differential mode cross current control loop based on stationary frame parameters.
