A cross current control system for multiple, parallel-coupled power converters
includes common mode chokes, local cross current feedback controllers, and local
converter controllers. Each common mode choke is coupled to a respective power
converter. Each local cross current feedback controller is configured for receiving
common mode cross currents from a respective local cross current detector, calculating
a resultant cross current, and generating a local feedback control signal. Each
local converter controller is configured for using a respective local feedback
control signal to drive the respective power converter in accordance with a coordinated
switching pattern. An integral choke assembly includes a common mode choke and
a differential mode choke with common and differential mode choke cores configured
with at least one magnetic flux path being shared by magnetic flux generated by
common mode coils and differential mode coils.
