SYSTEMS AND METHODS FOR ADVANCED DIAGNOSTICS IN MODULAR POWER CONVERTERS

摘要

A power conversion system (500) is provided. The power conversion system includes a plurality of power conversion modules (502) 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 (504) configured to calculate a difference between a reference current and an output current of the power conversion module, and a processing device (506) communicatively coupled to the current unbalance detection circuit and configured to perform processing using the calculated difference.
