This work investigates the analysis and design issues related to a boost DC/DC converter with soft switching. It provides a thorough explanation of the converter's working principles as well as a thorough examination of all of its operating modes.The suggested design enables zero-voltage switch activation by using a resonant circuit made up of two capacitors and an inductor. Along with providing a detailed description of the design concerns, the analysis also includes the computation of critical parameters for the resonant parts. This converter's ability to minimize voltage and switch losses is one of its notable advantages. Because of its soft-switching feature, this converter has the notable benefit of minimizing switching losses as well as the voltage and current strains on the circuit components. It also has a high switching frequency of operation. The advantages and disadvantages of this suggested structure are evaluated through a comparison with traditional topologies. Furthermore, the analysis validity is supported by simulation and experimental results using MATLAB software.
