Abstract
A multi-level converter includes first and second DC buses, a plurality of transistors coupled in series between the first and second DC buses and a clamp circuit configured to clamp a node joining a first transistor and a second transistor of the plurality of transistors. The converter further includes a bias circuit coupled to the clamped node, which may reduce or prevent voltage stress on the transistors. Related methods of operation are also described.
