“…The family of multilevel converter topologies called MLC 2 is proposed in [10]- [12], which introduce a multilevel clamping leg generating the multilevel neutral point potential for the main switching legs, and thereby, a new way to extend the output voltage levels of the converter was created.…”

“…1; it introduces the same switching legs as the well-known 3L NPC converter for both the clamping leg and the main switching legs. The dc bus in this topology is split into four equal sections (V 2 , V 1 , V −1 , and V −2 ), and the voltage stresses for the switches in the main phase legs (e.g., S m1 -S m4 ) are 3/2 times of that for the switches in the clamping leg (e.g., S c1 -S c4 ) [10]- [12]. The basic converter parameters are summarized in Table I, which is based on a typical grid-connected MV converter application for wind turbine systems.…”

“…Recently, a new series of diode-clamped-based multilevel topologies called multilevel-clamped multilevel converter (MLC 2 ) has been proposed in [10]- [12], which introduces additional switching leg(s) to generate multilevel neutral point potential for the main switching legs. Thereby, it creates an efficient way to extend the output voltage levels of the converter topology.…”

In this paper, a five-level multilevel-clamped multilevel converter (5L-MLC 2 ) topology is analyzed based on a typical grid integration application for renewable energy system. The loss and thermal distributions of the power devices in different switching legs are investigated and illustrated under rated condition. Afterward, a loss and efficiency evaluation method is proposed and applied which takes into account various injected reactive power ranges regulated by the grid codes. It is concluded that the loss and thermal distributions of the 5L-MLC 2 multilevel topology are unequal between the clamping switching legs and the main switching legs; it also shows a good and consistent efficiency characteristic under different output power ranges when complying with the grid codes.
