Multi-Port DC-DC Power Converter for Renewable Energy Application

As traditional energy sources diminish, renewable energy sources such as wind and solar power are crucial for sustainable power generation. The intermittent nature of these sources means that their output must be conditioned to meet grid requirements, typically through power converters. Current systems use separate converters for wind and solar, leading to high component counts and inefficiencies. The suggested system integrates various energy sources using a four-port converter: two input ports of wind and solar power, a bidirectional storage port, one an isolated load port. By adopting zero voltage switching, the system reduces costs, improves power flow management, and ensures seamless integration of renewable sources with the grid. This setup allows for more intelligent power flow between household users, the grid, and distributed generation units. The resulting DC voltage from the converter can be used directly for DC loads or converted to AC for household use, optimizing efficiency and resource use.
