摘要： Systems 10 and methods 300 for converting power are presented. The power conversion includes conducting load current through a first current path 92 of multiple current paths in a power conversion unit 12 using switches 60, diodes 74, or a combination thereof. The power conversion also includes blocking one or more additional current paths 94 of the multiple current paths in the power conversion unit 12 using one or more of the switches 60, one or more of the diodes 74, or a combination thereof. Furthermore, the power conversion includes reducing potential voltage stress on the one or more switches 60 by using one or more voltage stress reduction switches to reduce a voltage that is blocked by the one or more blocking switches or diodes 74 by connecting an end of each of the one or more switches 60 opposite to a blocking edge to an intermediate voltage node 84.
