To maintain a stable power supply, integrating multiple input sources is essential. A Multi-Input Converter (MIC) provides a more efficient solution by reducing the need for numerous passive components, which in turn minimizes cost, size, and weight compared to separate converters. This study introduces a dual-input boost converter with zero voltage switching (ZVS), utilizing a single auxiliary circuit to enable soft switching for all semiconductor elements. This design not only improves efficiency but also retains the advantages of multi-input converters. Additionally, a voltage multiplier is incorporated to enhance the voltage conversion ratio, achieving higher voltage gains. The theoretical analysis of the proposed converter is validated through experimental results, with efficiency measurements demonstrating a 3% improvement over conventional hard-switching designs.
