Abstract: (21 Views) |
In this paper, a high step-up soft-switched resonant converter is introduced, in which a resonant switched capacitor converter is combined with a conventional boost converter. The voltage gain of the introduced converter is much larger compared to the combined converters. In this converter, in order to increase the voltage gain, in addition to increasing the duty factor of the main switch, the number of switched capacitor cells can also be increased. Soft switching of the switches reduces switching losses and increases the efficiency of the converter. Continuous input and output currents, as well as eliminating the reverse recovery effect of the diodes, are other advantages of this converter. The proposed converter with a power of 200W and an output voltage of 380V is simulated in Spice software and the results obtained are in good agreement with theoretical analyses. |
