Isolated DC–AC Matrix Converter based Renewable Energy System for Improving Power Quality using Proportional Integral (PI) Controller Technique

Abstract

An Isolated DC–AC Matrix Converter based on high dynamic performance and wide range voltage regulation technique is applied and developed based on hybrid renewable energy systems. In the existing method Zeta converter based solar DC input source, it consists some drawbacks are sudden voltage loss, voltage is not stable, performance and efficiency is not constant is of the previous method when compared to the proposed method. So, to overcome the drawbacks an Isolated DC–AC Matrix Converter for Improve power quality using a renewable energy source. In this method input source is the Solar system, to produce a DC source from the absorption of sunlight without emitting any emissions. The single-phase matrix converter is made up of completely regulated bidirectional switches that allow the connecting of two single-phase systems, The photovoltaic energy is transmitted into the DC-DC converter module, which is connected to the battery and controller through a DC bus, and the other with current source characteristics is connected to the battery and controller at the same time. The photovoltaic energy is transmitted into the DC-DC converter module, which is connected to the battery and controller through a DC bus, and the other with current source characteristics is connected to the battery and controller at the same time. While collecting low input range, A Proportional Integral (PI) Controller sends pulses to a DC-DC converter and DC-AC inverter switches to evaluate photovoltaic (PV) input. The output result is a better gain of the output range, overcoming the existing drawbacks with improved power quality.
