Abstract
The reserve of conventional energy sources such as coal, natural gas, and crude oil are rapidly decreasing with increasing demand of electricity in the world. Also, the fossil fuels cause air pollution, global warming, and similar environmental problems. Therefore, recent studies have become widespread about renewable energy sources (RESs) such as biomass, hydropower, geothermal, wind and solar which are the most popular worldwide. Among other RESs, solar energy is assumed as the best alternative to conventional sources of energy. In this study, a micro-inverter (MI) is designed by using isolated boost converter on dc-dc side and full bridge inverter for dc-ac conversion. The power capacity of designed MI is rated at 10kW where the input voltage is 55 V while output voltage is converted to 230 Vrms at 50 Hz frequency. The boost converter is controlled by an INC MPPT controller. The PI controller and fuzzy logic controller are used to control the bridge inverter and the result of both the control methods have been compared.
Keywords: Micro-inverter, renewable energy sources, MPPT controller, fuzzy logic controller.
