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.

Abstract: A six-phase flat wire wave winding structure. Each phase of wave winding structure has a wire-in end, a wire-out end, and a wire located between the wire-out end and the wire-in end. The six-phase flat wire wave winding structure is applicable to a 2M-layer (M=1, 2, 3 . . . ) six-phase motor whose quantity of slots of each phase in each pole is q, whose quantity of stator slots is 6q (q=1, 2, 3 . . . ) times of a quantity of poles, and whose quantity a of parallel branches is 1 or 2. Each phase of the wave winding structure has conductors in all layers of a same stator slot, and the wave windings are uniformly and symmetrically distributed. In addition, problems that a flat wire winding process is highly difficult and manufacturing costs are high due to an increase in a quantity of phases of the six-phase motor are effectively resolved.
