Abstract: Inverter is one of the most important parts of renewable energy system. To overcome disadvantage of voltage source and current source inverter, Impedance source inverter (ZSI) ,which is buck boost inverter without the need of a dc -dc converter has been presented in recent year. To be an economic alternative to conventional inverters, Z source inverter should have higher efficiency and lower cost and sustain a high quality output voltage. For meeting these requirements we used various control method. An alternative power conversion concept recently proposed by Z-source converter because it has both voltage buck and voltage boost capabilities .In ZSI hasan unique X –shaped impedance network which couples converter main circuit to the power source. In this paper we deal with comparative analysis of different modified PWM control methods of Z source inverter (ZSI), which is also known as impedance source inverter . For obtain boosted outturn voltage, a shoot through state should be created followed by an active state. Therefore, small changes have been made by us in the classical three phase sinusoidal Pulse Width Modulation (PWM) technique to provide different control techniques for the ZSI. Simple boost control with triangular carrier wave, simple boost control with sinusoidal carrier waveform, maximum boost control, maximum boost control with third harmonic injection, constant boost control and constant boost control. In this paper, simulations of various shoot through Control techniques are performed for the same modulation index and outline parameters of the ZSI. The output voltage and output current of the inverter for the same input and load conditions are analyzed using MATLAB/SIMULINK.
