An Integrated MPPT And Inverter 12 VDC to 220 VAC with Current Limiter for Grid Connected Solar Cell System

Abstract

Abstract Research on the integration of current limiters in solar power plants connected to the electricity network with an on grid system. This study aims to regulate the flow capacity of the solar cell source to the load of electronic devices / needs of a house and connect to the national electricity network. The main features of the current limiting integration are: First, it avoids damage caused by excess current flowing; second, cut off in the national electricity network will not affect the flow of power to electronic devices; third, the characteristics of the components and the circuit configuration can be made simpler, which can improve the efficiency of the solar cell generation system. Built-in devices can be controlled simultaneously with easier synchronization. The performance of the developed system produces the power supply needed by electronic devices during the day / when there is sunlight that can continue to be supplied even though there is a power outage from the national electricity source. Thus, the results of simulations and experiments carried out with a prototype system in the laboratory are in accordance with the theoretical analysis.
