| Abstract |
BBC has equipped a DT3 vehicle of the Hamburger Hochbahn ("U-Bahn", subway) with asynchronous induction motor drives fed by current source inverter. A survey is given of the drive system. Some special features of the drive equipment are described with more detail: The input chopper needs no contactor for the change between driving and braking mode. The features of a two-quadrant-controller have been obtained by little additional expenditure compared with a one-quadrant-controller and by special control techniques. An input filter with 50 Hz absorbing resonant circuit ensures that line interference effects remain below the allowable limits. |
