Abstract: A power conversion system is provided. The power conversion system includes a plurality of power conversion modules connected in parallel, all power conversion modules of the plurality of power conversion modules configured to receive a pulse-width modulation control signal, each power conversion module of the plurality of power conversion modules including a current unbalance detection circuit configured to calculate a difference between a reference current and an output current of the power conversion module, and a processing device communicatively coupled to the current unbalance detection circuit and configured to perform processing using the calculated difference.
