This paper proposes a seven level Z-source multilevel inverter designed with three intermediate Z-source networks connected between the dc input source and inverter circuit. Multilevel inverters posses the advantage of reduced harmonics ,high-power capability and high-voltage level but switching losses are more due to the increased switching circuit. Switching losses can be minimized by either soft switching techniques or by modifying modulation technique by employing sinusoidal PWM-based techniques. The multicarrier pulse width modulation Cascaded multilevel inverter strategy enhances the fundamental output voltage and reduces total harmonic distortion. In this paper various simulation results are presented using MATLAB/SIMULINK.
