A grid-connected converter, also known as an inverter, is a device that converts DC (direct current) power from a renewable energy source, such as a photovoltaic (PV) system or wind turbine, into AC (alternating current) power that can be fed into the electrical grid. The converter synchronizes the voltage and frequency of the generated power with that of the grid, ensuring that the power is in phase and of the same frequency as the grid. This allows the renewable energy to be seamlessly integrated into the grid and used by consumers. Grid-connected converters also play an important role in power quality by regulating voltage, controlling current, and correcting power factor to reduce harmonic distortion and improve the overall performance of the grid. The use of grid-connected converters is essential for the integration of renewable energy into the grid and the transition towards a more sustainable and low-carbon energy system.

Grid-connected converter topology refers to the design and configuration of the electrical components used in a grid-connected converter system. Different topologies have been developed to meet the specific requirements of different renewable energy sources.

One common topology for renewable power is the three-phase grid-tied inverter. This topology is well-suited for large scale renewable energy systems, such as a solar PV arrays or wind turbines, and is designed to handle high power levels and operate with a high level of efficiency. It consists of three inverters connected in parallel, each of which is responsible for converting the DC power from one phase of the renewable energy source into AC power that is in-phase with the grid. This topology allows for a high level of redundancy, as well as the ability to handle fault conditions.

Another common topology is the two-stage grid-connected converter, which is designed for use with smaller scale renewable energy systems, such as residential or commercial solar PV systems. This topology consists of two stages: a DC-DC converter, which boosts the DC voltage from the renewable energy source to a higher level, and a DC-AC inverter, which converts the DC power into AC power that is in-phase with the grid. This topology is less complex and more cost-effective than the three-phase topology, but it is less efficient and not as well suited for handling high power levels.
