<p>Disclosed is a multi-level medium voltage inverter capable of increasing the redundancy of the entire system. The multi-level medium voltage inverter according to the present invention, which outputs a three-phase voltage to a three-phase motor by receiving three-phase power, comprises: a plurality of unit power cells, wherein one or more unit power cells are connected in series to output a single phase voltage, and the unit power cells forming each phase voltage form one level to form multiple levels; and a module type phase displacement transformer which converts three-phase power and applies the three-phase power to the three unit power cells forming one level, wherein the module type phase displacement transformer is configured to correspond to the multiple levels.</p> |
