“…Here the inductors are energized by capacitors at shoot through state and energy in inductors are discharged to dc-link that increases the voltage gain [6]. inverter cost and size are increased when the high voltage stress on its capacitors of impedance network and the PV applications required normally boost voltage ratio through a day so converter is connected between them and it needed to do high gain conversion and steady state AC -DC conversion but it can be done with single stage using ZSI [7][8].…”

“…The boost factor for switch inverter is same as the conventional inverters [9][10]. The capacitor stresses are reduced using switched inductor and however the traditional ZSIs have some demerits like high stress on capacitors and semiconductor devices, low voltage capability and inrush current [11][12]. The Z-source converter is also suitable for renewable energy sources like solar, wind and fuel cell etc.…”

Quasi inverter is designed in this paper to enhanced gain operation using sliding mode controller (SMC) with Z-source inverter (ZSI). It has boost voltage conversion at low ratio in duty cycle and output voltage quality is improved by high modulation index. Direct current (DC) is converted to alternating current (AC) with higher frequency pulse width modulation (PWM) signals. To reduce the inrush current in starting period it draws a low voltage at capacitors. This proposed inverter consists of common ground to source as well as bridge rectifier. Moreover, the ripple current is almost negligible in this ZSI. This paper proposes the ZSI with impedance of two switches network and the theoretical analysis done also it is confirmed in MATLAB/Simulink.
