    摘要: A wide-voltage-range converter with a power-supply-side converter unit and a load-side converter unit includes a step-up converter electrically connecting the DC voltage sides of the power-supply-side converter unit and the load-side converter unit, respectively. The wide-voltage-range converter further includes a bidirectional switch and a turn-off semiconductor switch as converter unit valves in each phase (R, S, T) of the power-supply-side converter unit. The power-supply-side converter unit also includes a filter on the AC voltage side, whereas the load-side converter unit includes a DC voltage capacitor on the DC voltage side. The wide-voltage-range converter operates at a specified output voltage without derating.

    摘要: A power-line filter for operation with a converter is provided having a regulated voltage source and sinusoidal phase currents, with the power-line filter helping to eliminate interference voltages particularly in the frequency range from 2 kHz to 150 kHz, which are normally not taken into account. The leakage currents to ground, in this context, can be minimized to the point that it is possible to operate the converter in an (AC/DC sensitive) Interference Filter (IF) protective circuit-breaker.

    摘要: A control arrangement according to an example embodiment of the present invention by means of which it is not only possible to minimize the harmonic content when energy is fed into/recovered from the three-phase network into a variable voltage link, but which also allows corresponding switching losses to be minimized. Furthermore, the control arrangement is also robust with respect to failure of at least one network phase, and is robust with respect to phase fluctuations. This is achieved in that not only digital angular function values whose phases are correct but which are phase-shifted equidistantly with respect to one another are stored in one or more function memory elements, but also associated digital signals which represent respective mathematical signs of these angular function values. These digital mathematical sign signals are compared in a comparator stage with digital mathematical sign signals measured via a phase detector of the individual network phases and if these compared values fail to coincide with one another, an inhibit signal is generated, by means of which the drive pulses for the converter active devices in the converter can be inhibited.

    摘要: A method and a circuit arrangement for shaping any actual a.c. voltage characteristic into any reference a.c. voltage characteristic are described, which store the excess power in voltage overshoots in the form of a current in a current storage device using power electronic switching elements, and thus they compensate for the power deficiency when there is a voltage shortfall. The power electronic switching elements are driven by a digital automatic state machine through appropriate control pulses so that there is no fixed switching rate. The preferred field of application is for active filtering of the voltage of an electric three-phase or a.c. power supply system.
