This paper presents an analysis of single phase Quasi Z-Source (qZS) Inverter based grid connected system. Quasi Z-Source DC to DC converter consists of unique impedance network which consists of inductors and capacitors. To boost DC voltage, traditional boost converters were used. But it has many disadvantages like dual stage converter, complexity in control, losses are high. On the other side the quasi-Z-Source Inverter (qZSI) is an alternative converter that can boost the input voltage. It has many advantages like single stage conversion, lesser losses, reduced component rating as well as size of components and provides continuous input current. Quasi-ZSI provides boost capability with single stage conversion which ultimately reduces the switching losses. qZSI allow the shoot through state which is responsible for the boosting of the input voltage to the higher values and avoids the risk of damaging switches in converter circuit to make the circuit more reliable. Theoretical analysis of boosted voltage and control methods for the qZSI system are investigated in this paper. Both simulations and theoretical analysis will be presented to demonstrate the proposed concept.
