Abstract
An adaptive control method for a fault control-oriented economically-integrated medium-voltage grid-connected device with a silicon carbide (SiC) module, includes: calculating a three-phase bridge arm modulation wave and a fourth bridge arm modulation wave; obtaining a three-phase bridge arm neutral point clamped (NPC) circuit switching signal; obtaining a three-phase bridge arm NPC circuit output voltage; obtaining a fourth bridge arm NPC circuit switching signal; obtaining a fourth bridge arm NPC circuit output voltage; calculating a voltage-stabilizing active vector of each submodule of a cascaded H-bridge (CHB) circuit; obtaining a three-phase bridge arm CHB circuit switching signal; obtaining a fourth bridge arm CHB circuit switching signal based on the fourth bridge arm modulation wave, the fourth bridge arm NPC circuit output voltage, and the voltage-stabilizing active vector of each submodule of the CHB circuit; and performing adaptive control of a grid-connected device based on the CHB circuit switching signal.
