【Abstract】 In the fuel cell DC/DC converter,in order to reduce the ripple current and ensure the output stability,the experimental topology used six cross fault parallel circuit,which could effectively reduce the current ripple and reduce the inductance volume.In addition,a new control model was proposed,which was controlled by the current double loop and the outer loop by the input current to ensure the constant input current.And the inner ring realized the power demand of the load through the output current.更多还原
