| Abstract: | A ZVS (zero-voltage-switching) full-bridge phase-shift converter with voltage-multiplier was proposed for high voltage and high power applications. The operation principle and characteristics of the convener were analyzed. With the equation of the primary current RMS deduced, a new design method for full-bridge phase-shift dual voltage converter was proposed and established. Then, the converter was optimized by MATLAB. Finally, the experiment results verified the analysis, deduction and the optimal design results. |
