Abstract: This paper present the comparison of quasi impedance source inverter (QZSI) with boost switched based quasi impedance inverter (BSL-QZSI). Mainly this type of inverter is used for interfacing low voltage dc to high voltage ac conversion application for reducing converter stages and components count. The BSL-QZSI has additional switch for controlling the input power flow through inductor. The QZSI does not require control switch for input side. Both inverter circuits are simulated using sine PWM technique. Their performance is compared. The QZSI circuit has better performance compare than BSL-QZSI inverter. Sine PWM method is used to reduce the harmonics and improve the output voltage control.
Keywords: Quasi impedance source, boost converter, shoot through and harmonic.
