Jun Wang, Rolando Burgos, Dushan Boroyevich
Issued: June 21, 2022

Aspects of hybrid-current-mode switching-cycle control are described. In one embodiment, a peak current mode is selected to control a switching power cell. The switching power cell is in an arm of a phase leg of a modular multilevel converter. The phase leg includes an upper arm and a lower arm, and the switching power cell includes a capacitor and at least one switch. At least one switch control signal switches the switching power cell according to a peak current mode based on at least one arm current boundary crossing identified for the arm.
