Abstract:

 A novel zero voltage and zero current buck converter with soft switching was proposed using the coupled inductor instead of the filter inductor. The detailed theory analysis of the converter’s each operation stages was conducted. The conditions of obtaining soft switching and the designing procedure of main circuit were presented. The performances of the proposed buck converter with different turn radios were discussed. The new circuit was analyzed by simulation. The theoretical and simulation results illustrate that all power switches can achieve soft switching in the new circuit. A 50 kHz buck converter prototype of 48 V input, 32 V output with soft switching based on coupled inductor was constructed. The experimental results accorded with the theoretical and simulation results. The correctness of the theory and design of the converter was validated, and the measured maximum efficiency reached 96.5%.
