A Comparative Topologies in Grid Connected Photo Voltaic System for Efficient Behavior
The power delivered by a PV system consisting of one or more photovoltaic cells is dependent on the irradiance, temperature, and the current drawn from the cells. Maximum Power Point Tracking (MPPT) is used to obtain the maximum power from these systems. Grid-tied inverters are the key components of distributed generation system because of their function as an effective interface between renewable energy sources and utility. In this paper, Perturb and Observe (P&O) and Incremental Conductance (IC) MPPT controllers are modeled and comparison is carried out. Recently, there has been an increasing interest in the use of transformer less inverter. The leakage current issues of transformer less inverter depends on the topology structure and modulation scheme, so it have to be addressed very carefully to meet the safety regulations. In order to eliminate the leakage current, OH5transformer less inverter topology is proposed and compared with switching inverter. The results concluded that using ICalgorithm the efficiency will improve comparatively. With the use of transformer less OH5 inverter along with ICalgorithm reduction in size and cost is observed. The improvement in efficiency with OH5 inverter is possible because of using five MOSFET switches. With usage of MOSFET switches switching losses and dead time is reduced. The leakage current is less in OH5 inverter compared to all other topologies proposed in reference. So isolation between grid and PV system is possible and safety of operating person is improved.
