    摘要: A hybrid AC and DC distribution system (200) includes a doubly fed induction generator (DFIG) (204;504), a DC distribution bus (214), an AC/DC converter (218;506), an AC distribution bus (216), and a DC/AC converter (220;508). The DFIG includes a rotor (224) and a stator (226), and is configured to generate a first AC power at the rotor and a second AC power at the stator. The AC/DC converter (218;506) is coupled to the rotor and the DC distribution bus (214). The AC/DC converter (218;506) converts the first AC power to a first DC power at a first node (228;510) for delivery to a first load (206,210) through the DC distribution bus. The DC/AC converter is coupled between the first node and a second node (230;512) coupled to the stator (226) and the AC distribution bus (216). The DC/AC converter converts the first DC power to the second AC power at the second node (230;512) for delivery to a second load (206,208) through the AC distribution bus (216).

    摘要: An uninterruptible power supply (UPS) (120;200) includes a line terminal (202), a load terminal (204), a double-conversion circuit (216) coupled in series, and further includes a bypass circuit (218), and a synchronize circuit (220). The line terminal couples to a doubly fed induction generator (DFIG) (170). The load terminal couples to a load (130) having a demanded power. The double-conversion circuit regulates grid power from the line terminal to the demanded power at the load terminal. The bypass circuit is coupled between the line terminal and the load terminal, and configured to deliver regulated power generated by the DFIG to the load terminal when the grid power is lost. The synchronize circuit is coupled between the double-conversion circuit and the DFIG, and, when the grid power is lost, the synchronize circuit injects a current through the double-conversion circuit and into the DFIG, synchronizing the regulated power generated by the DFIG to the demanded power.
