Microchip Technology has developed a fully digitally controlled, grid-connected solar micro inverter reference design with an advanced, high-efficiency topology. Complete documentation, including software, schematics and application note, is available.
The solar power industry is evolving to meet the requirements of a changing landscape, as it moves from a cottage industry to mass production. Solar design engineers are being challenged to optimise energy harvesting, reduce installation costs, and improve system reliability and efficiency while standardising their designs. This reference design aims to enable them to achieve these goals through digital power conversion techniques, supported by the features of Microchip’s dsPIC33F ‘GS’ series of digital signal controllers (DSCs). The reference design connects to any standard solar panel and converts the panel’s DC output into AC power, which can then be fed into the public power grid. In a real-world application, multiple units can be connected together to achieve the desired power output.
The reference design boasts peak efficiency of 95%, power factor higher than 0,95, output current THD below 3%, maximum power point tracking of 99,5% and night time power consumption of less than 1 W. It works with any photovoltaic (PV) panel that supplies a maximum 220 W output, and it comes in two versions supporting either 110 V or 220 V power grids.
