Abstract
Disclosed herein is a modular, scalable, and galvanically isolated power electronics converter topology for medium voltage AC (MVAC) to DC or high voltage AC (HVAC) to DC power conversion. A disclosed modular converter can comprise a low-voltage direct current bus and a centralized controller configured to regulate the low-voltage direct current bus. The modular converter can further comprise a plurality of three-phase blocks connected in series. Individual three-phase blocks of the plurality of three-phase blocks can comprise a plurality of single-phase modules connected in an input-series output-parallel configuration. The modular converter can further comprise a filter connected between a grid input and the plurality of three-phase blocks and a pulse-width modulator configured to generate encoded gate pulses for the individual three-phase blocks of the plurality of three-phase blocks.
