Use of conventional two ¨C level pulse width modulation (PWM) inverter provide less distorted current and voltage but at cost of higher switching losses due to high switching frequency. Multilevel inverter are emerging as a viable alternative for high power , medium voltage application. This paper compare total harmonics distortion in three level and five level diode clamped multilevel inverter. Diode ¨Cclamped three phase topology is considered for study. A sinusoidal PWM technique is used to control the switches of the inverter. Simulation study confirms the reduction in harmonics distortion. %K - Harmonics %K multilevel inverter %K pulse width modulation %K Total harmonics distortion %U http://www.ajer.org/papers/v2(7)/S027159166.pdf
