This paper proposes the new soft switching DC-DC converter. We reported the experimental results of the new soft switching DC-DC converter. The proposed converter is to resonate between the leakage inductance of the transformer and the parasitic capacitances of the main switches for zero voltage switching. The voltage stresses of the two switches are the input voltage, it can improve the efficiency and a reduced height used two transformers. Theoretical analysis of the converter along with experimental results is provided. Finally, a 3.3V/20A prototype converter operation at 100kHz is built and experimental waveform verifies the analysis.
