1. Improved Transformer Less Solar Inverter for Solar Grid Using Constants Power Generation

AUTHOR NAME : Shrikant P. Khadase, Prof. N. A. Bodkhe

ABSTRACT : There are two main types of distributed solar power generation system stand-alone system and grid-connected system. In grid-connected system usually are equipped with additional transformer to transfer the energy from solar power to the grid. However, it has resulted in considerable cost in providing these systems. Therefore, in this research develops boost transformer less solar inverter system. The proposed system consists of a boost converter and transformer less inverter. Boost converter is used to increase the dc voltage yield by photovoltaic (PV) and delivered to the grid by mean of transformer less inverter. In order to maximize the power from PV, the proposed system is also designed with Maximum Power Point Tracking (MPPT) by changing the value of modulation index in the transformer less inverters. From the simulation results show that the system can work effectively in a variety condition such as light intensity changed and fluctuating in the grid voltage side. The algorithms utilized for MPPT are generalized algorithms and are easy to model or use as a code. The algorithms are written in m files of MATLAB and utilized in simulation.
