Design of a grid connected system using proteus software

Nowadays the usage of renewable energy source is being encouraged in developing countries to meet the power shortages. The produced supply must follow the precised guidelines, so that the supply can be connected to the grid system. In this work, a grid connected module is developed using a DC - DC converter and conventional H - bridge inverter. The aim of the proposed methodology is to reduce the size of the filter used across the inverter and it is achieved. This is done by applying SPWM wave to the DC - DC SEPIC converter and the H - bridge inverter is operated at normal power frequency.
