Abstract— Solar energy is inexhaustible, freely available and clean source of energy generation. The solar pv system generates variable output, its operation depends upon the solar irradiance. In this paper, a single phase transformer less multilevel inverter is used for solar pv application. A constant voltage of 330 V DC is produced by DC-DC boost converter from variable input voltage. By using H-bridge multilevel inverter DC voltage is converted into sinusoidal 230 V AC Voltage. The system is modeled using Matlab. Two, multilevel inverters are compared to show reduced total harmonic distortion (THD).

Keywords— DC-DC converter, H-bridge multilevel inverter, THD
I. INTRODUCTION
The large usage of the fossil fuels, like the oil, the gas and the coal, results in greenhouse effect and pollutes the atmosphere. Meanwhile, there is a huge conflict between the fossil fuels supply and the global energy demand leading to a hike oil price in the market. The energy shortage and the atmosphere pollution have been the major limitations for the human development. In order to meet the rising global energy demand from environmental friendly sources, various renewable energy are given attention [1]. From , all the renewable energy sources , solar energy is the most rapidly increasing renewable energy source because it is inexhaustible, freely available and clean source of energy generation[2].The power obtained from solar energy are connected to the grid for better utilization of
