A system includes a voltage converter and a controller for controlling the operation of the voltage converter. The voltage converter includes a plurality of legs, wherein each leg includes a first and a second set of silicon (Si)-based power devices. The first set of Si-based power devices includes a first and second Si-based power devices connected to each other at a first interconnection node and the second set of Si-based power devices includes a third and fourth Si-based power devices connected to each other at a second interconnection node. The first and second set of Si-based power devices are coupled across a first and second DC voltage sources respectively. A first set of Silicon-Carbide (SiC) based power devices is coupled across the first and second interconnection nodes. The system also includes a snubber capacitor connected across the first and the second interconnection nodes.
