Performance Analysis of Input Parallel Output Series Full Bridge Converter Considering Parasitic Effects

The Input Parallel Output Series (IPOS) Full-Bridge DC-DC converter offers significant advantages over the conventional Full-Bridge converter by connecting multiple modules in parallel on the input side and in series on the output side. This configuration enhances voltage gain, improves overall efficiency, reliability, and scalability. MATLAB simulations are carried out to demonstrate the IPOS converter's superior performance in terms of voltage output and efficiency. Additionally, the IPOS design provides enhanced redundancy; if one module fails, the others continue to operate, ensuring uninterrupted performance. This makes the IPOS Full-Bridge converter ideal for applications in renewable energy systems, electric vehicles, and other high-performance power management scenarios.
