چکیده
Recently, several numbers of multilevel inverter topologies have been presented that the numbers of power electronic devices have been reduced. This paper presents a novel single-phase topology for multilevel inverter. The proposed topology is based on cascaded connection of basic units. This topology uses minimum lumber of power electronic components such as IGBT, gate driver circuit and antiparallel diode. For proposed topology, two methods are presented for determination of dc voltage sources values. The propose topology is used in medium and high-voltage applications. The proposed topology is compared with other topologies which recently have been proposed. MATLAB/SIMULINK software is used for simulation. Keywords–Multilevel inverter, classical topologies, modulation control, total harmonic distortion.
