From the simulation results it can be easily concluded that two stages grid connected PV inverter has better and stable response as compared to the single stage grid connected PV inverter. Two stages operation has proved to have high efficiency, almost unity power factor and higher accuracy of tracking reference voltage.
Considering the aforementioned drawbacks of both multi-stage and two stage inverters, single-stage inverters which boost the PV output, employ MPPT and invert the boosted DC into AC using only a single power electronic circuit are becoming popular these days.
A multi stage inverter employs more than one power processing stage where in one or many stages achieve the task (s) of boosting the DC output from PV array and/or galvanic isolation with the final stage being the conversion of the boosted DC into high-quality AC.
SSI does the boosting of DC and inversion of the DC to AC using only a single circuit and hence the name Single-Stage Boost Inverter. SSBI give us the advantage of reduced and robust circuitry along with reliability and efficiency. This paper presents a review of the various (however not all) SSI topologies in PV systems. 1. Introduction
Single stage grid connected PV system In single stage operation the photovoltaic array is directly connected with the utility power network through PV inverter as shown in Fig. 1. In this case the maximum power point tracking and delivery of real power to the grid is achieved by the inverter stage itself.
Single-phase grid-connected inverters with DC-links are widely used in residential PV systems. In such a PV inverter, the DC-link capacitor plays an important role of decoupling DC power and AC power and buffering energy to ride through power disturbances.
