This document presents a new multilevel inverter structure that can be used in high-power applications. The proposed topology uses a cascaded connection of basic units, each consisting of a full-bridge inverter. This reduces the number of required components compared to other multilevel inverter structures. Two methods are presented for determining the DC voltage source values: a symmetric method where all sources have the same value, and an asymmetric method where the values differ. A multi-carrier PWM strategy is used to generate the switching signals. Simulation results show the 25-level inverter generates output voltages and currents with total harmonic distortions of 5.57% and 0.083%, respectively.
