    • Converter and method for controlling a converter with power semiconductor switches, having a filter (1) which is connected to the power semiconductor switches and having a drive circuit (4) which is connected to the power semiconductor switches for the purpose of modulation, wherein, as a result of the modulation, a fundamental at a fundamental frequency (fGS) is generated in a passband (P) of the filter (1), modulation products are generated in a first frequency band (FB1), in a second frequency band (FB2) and in an intermediate frequency band (ZFB) which is formed between the first frequency band (FB1) and the second frequency band (FB2), the modulation products in the intermediate frequency band (ZFB) are reduced in comparison with the modulation products in the first frequency band (FB1) and the modulation products in the second frequency band (FB2),; and the intermediate frequency band (ZFB) is generated, in a resonant range (R) of a resonant frequency (fres) of the filter (1), between the passband (P) and an attenuation range (D) of the filter (1). A converter having an output-side sinusoidal filter whose dimensions have been reduced is thus obtained.

    • The present invention provides a current regulating method and associated apparatus for a voltage-injecting converter, wherein a flux-producing current component and a torque-producing current component of an actual current vector are regulated to corresponding components of a required current vector, whereby a precontrol variable is superimposed on each controller manipulated variable. According to the invention, the torque-producing controller manipulated variable acts on the flux-producing controller manipulated variable with delay as a function of a frequency variable, thereby providing a current regulating method which combines the advantages of two-component current regulation and active current regulation. This dual-action current regulation advantageously operates without requiring a structural switch between the two forms of current regulation.

    • This invention relates to a device for spanning expansion gaps in bridge decks or roadways. The invention provides a small, simple and low cost edge channel member of U-shape which may be welded to one type or a variety of different commericially available steel sections in accordance with any particular needs. Screws accessible from above are provided to retain the edge portions of an elongate body of flexible resilient elastomeric material which spans the expansion gap. Thus, the invention permits the installation of expansion joints for any desired thickness of the wearing course and any type of fastening to the concrete base course.
