MULTI-LEVEL AND MULTI-PHASE CONVERTER AND CONTROL METHOD FOR OPERATING A MULTI-LEVEL AND MULTI-PHASE CONVERTER

원문 (중국어)

The disclosure concerns a multi-level multi-phase converter, comprising: a transformer with multiple phases; a primary side circuit connected to a primary side of the transformer, the primary side circuit comprising multiple parallel connected primary switch legs having primary switches, wherein a number N of phases of the transformer corresponds to that of primary switch legs; and a secondary side circuit connected to a secondary side of the transformer, the secondary side circuit comprising multiple secondary rectifier legs with secondary rectifier elements, wherein the secondary rectifier legs are connected in parallel; wherein each of the primary switch legs comprises multiple stacked primary half-bridges connected in series; and each phase of the primary side of the transformer is connected between two primary half-bridges connected in series. The disclosure also concerns a control method for operating the multi-level multi-phase converter.
