Single Phase Module Integrated Converter Topology for Microgrid Network

Abstract: The centralized approach of the traditional power grid would leads to national power blackout resulting in research for alternate solutions. This effort leads to the concept of smart grid. The single phase PV panel connected with micro inverter became efficient in now-a-days. The proposed topology deals with the analysis of single phase grid connected PV system with the help of microinverter topology. The work describes the representation of micro inverter for neglecting the domino effect. This paper, differentiate the microinverter from the string inverter in order to increase the efficiency of the micro grid. The main aim of the grid tied PV micro inverter is to convert the raw solar energy from the PV panels and feed it to the grid with high efficiency and high power quality. This topology consists of the buffer and cycloconverter to increase efficiency. The main advantages of the proposed topology are: 1) Eliminating the double frequency effect, 2) There is no requirement of additional circuitry and 3) Using long lifetime capacitors. The proposed approach is analyzed and experimentally verified.
