摘要

The analysis and design considerations of a soft-switching boost dc/dc converter have been presented. Operating principles of the converter have been completely presented, as well as the thorough analysis of the operating modes. In the analyses, all the equations related to the voltages and currents of the elements have been attained, and by using these equations the maximum values of them have been calculated. In the proposed structure, due to the resonant circuit, which consists of an inductor and two capacitors, the switches are turned on with zero voltage. In addition to the operating modes analysis, the values needed for the resonant elements have been calculated, and the design considerations have been presented in detail. One of the advantages of the proposed converter is the decrease in switching losses, besides the reduction of the voltage and current stresses of the circuit components, due to soft-switching feature. Another advantage of the proposed structure is its high switching frequency. In this literature, in order to evaluate the advantages and disadvantages of the proposed structure, there has been made a comparison with the conventional topologies. Moreover, the correctness of the presented analyses has been validated by experimental and simulation results, using PSCAD/EMTDC software.
