Abstract
This paper is the research on the development of power conversion system for the fuel cell. In composing the DC/DC converters which have high boost voltage ratio, unlike the conventional method a new multi DC/DC converter system is proposed that the diode and the condenser and the reactor can be reduced by connecting the secondary side output of the transformer. In this system the rectifier part and the filter part of the secondary side in the power transformer that is connecting in series are composed into a single module, which is the strong advantage and the number of level can be easily increased. A new variable shift phase switching method is also suggested that it makes possible to reduce the output voltage ripples in the proposed system. All the factors mentioned above have been verified through simulations and experiments, and the proposed converter is considered very useful in the demanded load which requires a wide of the output.
