| Abstract: | A novel interleaving push-pull converter was presented to meet the demands of high power density and low output ripple in a power supply.The converter was a parallel connected converter,which was made up of two push-pull converters that use the same filter capacitor.The combined converter had many advantages such as low current stress and conducting losses of power switches,low output current ripple,small volume of input and output filters and so on.This paper analyzed modes of the combined converter in detail and gave the design method.The experiment results prove the validity of analysis and design method. |
