Multilevel inverter technology has emerged as a very important alternative in the area of high-power medium-voltage energy control. It offer several advantages as compared to the hardswitched two-level pulse width modulation inverters, such as their capabilities to operate at high voltage with lower dv/dt per switching, high efficiency, low electromagnetic interference. The THD and switching losses will vary with respect to topology and control technique adopted. This paper aims at comparing the performance of three phase five and seven level diode clamped inverter with respect to their THD, switching losses and number of components. The performance is verified through extensive simulations on MATLAB Simulink platform for IGBT device.
