Abstract

This paper presents an application of stand-alone Photovoltaic (PV) systems for improving the total harmonic distortion (THD) of line input current in twelve-pulse AC/DC power conversion systems. In these control systems, the trapezoidal voltage is generated from a PV stand-alone and injected into line input voltage. The process control system uses a 12-pulse diode rectifier, using a conventional 3-phase bridge 6-pulse diode rectifier. The results are from experiments and simulation of the trapezoidal voltage waveform. The results of the process can reduce the total Harmonic current (THD) of line input current. The simulation results by MATLAB program are used as a guideline for analyzing and designing the parameters of a control system. The experimental results show, that the performance of the proposed control
