Abstract:
A multilevel converter system is provided. The multilevel converter system includes a multilevel converter and a short-circuit protection circuit. The multilevel converter includes a first segment and a second segment electrically connected to the first segment, wherein the first and second segments are each configured to convert a first current to a second current. The first segment includes a plurality of first switches. The second segment includes a plurality of second switches. The short-circuit protection circuit is electrically connected to the multilevel converter, wherein the short-circuit protection circuit includes at least one electrical component that is electrically connected in parallel with at least one of the plurality of first switches and the plurality of second switches. The short-circuit protection circuit is configured to protect the plurality of first switches and the plurality of second switches from a short-circuit current during a short-circuit condition.
