The quasi Z source inverters have been proposed as an alternative to power conversion concepts as they can both buck or boost input voltage. This paper explores various modulation technique for voltage fed quasi Z-source Inverter. In recent years several modified control technique have been proposed to control the quasi z source inverter in an efficient way. The comparison analysis is performed between various modulation techniques in quasi z source inverter. The modulation techniques are simple boost control, maximum boost control, and maximum constant boost control. From the study maximum constant boost control technique was found to be better than other sinusoidal pulse width modulation
