© 2018 IEEE. This paper proposes a novel five-level single-phase inverter topology. The inverter uses eight power switches, two capacitors, one inductor, one diode, and a small LC filter at the output. Compared to other multilevel inverters, the proposed inverter can achieve up to 400% more output voltage for the same DC link voltage. As a result, it requires the only of the conventional multilevel inverter topology. The operational states are discussed in brief with the theoretical explanation. A comparison table is illustrated to show the importance of proposed topology compared with existing topologies. The key simulation waveforms are presented, and the preliminary experimental results are carried out for the proposed topology to verify the simulation and theoretical analysis.
