In this study, a new converter featuring an auxiliary circuit configuration is presented, designed to facilitate soft switching conditions while minimizing the number of components used. This auxiliary circuit is innovatively developed to achieve zero voltage switching (ZVS) and effectively recover snubber energy to the input side, thereby enhancing the converter efficiency. Furthermore, the deliberate integration of coupled-inductors into the converter's design significantly boosts its gain while reducing voltage stress on the switching components. The modular architecture of the auxiliary circuit allows for the addition of circuit branches and an increase in power capacity without requiring extra components for its auxiliary circuit. To evaluate the performance of the proposed converter, extensive simulations were performed using PSPICE software, along with the construction of a laboratory prototype capable of operating at 170W. The alignment between the experimental results and simulation data strongly supports the theoretical analysis, illustrating the converter's potential for efficient power conversion in renewable energy systems.
