Comparative Study on AC Square and Three-Level Wave Form of Photovoltaic and Wind Power Hybrid Single Phase Inverter
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 10
Abstract
This paper presents a new topology of three-level single phase photovoltaic (PV) and wind power hybrid inverter. It consists of four main circuits; they are a hybrid controller circuit, a charger circuit, a pulse driver and full bridge circuit. The inverter is installed in front of Electrical Energy and Industrial Electronic Systems (EEIES) Cluster, Universiti Malaysia Perlis, Northern Malaysia. Objective of this paper is to compare current total harmonic distortion (CTHD) of the alternating current (AC) square and three-level wave of PV and wind power hybrid single phase inverter. In this research, the AC waveforms are developed and created by a microcontroller PIC16F627A-I/P. The result shows that for a load of 20 W AC water pump, the AC waveforms effect on the CTHD. The CTHD is lower when the PV and wind power hybrid single phase inverter is formed as AC three-level wave than as AC square wave. Average CTHD of the square wave is 19.84% and average CTHD of the three-level waveform is 7.56%. Hence the improvement in the average CTHD obtained when a three-level wave of the PV and wind power hybrid single phase inverter is used will be about 62% if compared with the square wave. It indicates that the PV and wind power hybrid single phase inverter formed as AC three-level wave is better than as AC square wave.
