Performance Investigation of Stand-alone Photovoltaic System with Three Phase Developed H-Bridge Multilevel Inverter

Abstract

In this paper a three-phase developed H-bridge multilevel inverter (MLI) based stand-alone solar photovoltaic system is presented. The proposed MLI utilizes a smaller number of components. This in turn, reduces the complexity in architecture and control circuits. When this thirteen-level MLI is connected with PV panels, will reduce the harmonics with smaller number of components. Furthermore, Phase disposition pulse width modulation (PD-PWM) technique is opted as a control scheme for controlling multilevel inverter switching. The obtained total harmonic distortion is very less. Finally, the performance of the proposed MLI is validated by simulation.
