  • Multi-phase converter topology for multi-phase and single-phase operation
    Patent number: 11451132
    Abstract: A multiphase converter topology is used for the transmission of electrical energy from an AC voltage input with m grid phase connections to a DC voltage output or vice versa. It has a power part with half-bridges for switching currents, an AC voltage filter between the power part and the AC voltage input, and DC voltage block(s) connected between the power part and the DC output. The AC voltage filter has alternating voltage filter stage(s) with m+1 input connections, m+1 output connections and a ground connection. The m grid phase connections are thereby connected in parallel to one another and form a first phase connection for the connection of a single-phase AC voltage. A neutral conductor connection of the AC voltage filter forms a neutral conductor connection of the AC voltage input and a second phase connection for the connection of the single-phase AC voltage.
