Abstract
A capacitor structure and a power converter are provided. The capacitor structure includes a parallel cell combination, and the parallel cell combination includes a plurality of cells and a plurality of current collectors. In the parallel cell combination: the cells are connected in parallel, and the poles connected in parallel are respectively connected with other devices through corresponding confluence points. Same poles of two adjacent cells are connected through a corresponding current collector, and the current-carrying specifications of each current collector is lower than the current-carrying requirements of a confluence point of a corresponding pole. That is to say, a conductor that implements the parallel connection of the cells is no longer a whole copper plate, but the individual current collectors, thus realizing the reduction of the cost of the conductor material.
