摘要： A frequency converter with a rectifier on an input side and a backup capacitor arranged downstream of the rectifier. Input-side phases of the rectifier feed the backup capacitor via multiple half-bridges of the rectifier. The input-side phases are connected to grid-side phases of a multiphase supply grid via a pre-circuit. Each grid-side phase is connected to an input-side phase within the pre-circuit via a phase capacitor. Each grid-side phase is additionally directly connected to another input-side phase within the pre-circuit via a switch and the grid-side phases are short-circuited with the input-side phases when the switches are closed. Each phase capacitor connects two grid-side phases or two input-side phases together. The frequency converter has a control apparatus which keeps the switches open when pre-charging the backup capacitor and closes the switches when a specified charge state of the backup capacitor is reached.

摘要： The invention relates to a DC voltage network having a plurality of sections (1) which can be connected together and separated from one another individually or in groups via a respective switch element (5). A pre-charging circuit (10) has diode groups (11), a switch device (12), an energy transmission path (13), and a controller (14). Each of the sections (1) of the DC voltage network is coupled to the energy transmission path (13) via at least one respective diode group of the diode groups (11). The energy transmission path (13) is consistently the same for the diode groups (11). The controller (14) transmits a control signal (S) to the switch device (12) in order to pre-charge sections (1), and the switch device (12) thereby switches the energy transmission path (13) for all of the sections (1) coupled to the energy transmission path (13) so as to be conductive,

摘要： A rectifier has at least three outputs at which the rectifier provides a high potential, a low potential and at least one medium potential. Phase voltages of a supply grid can be supplied to the rectifier via feed lines. Inductors are arranged in the feed lines. A clamping circuit has two diode circuits that are connected in series. One of the end points of the series circuit is connected to an output at which the rectifier provides one of the medium potentials. The other end point is connected to another output. The node is connected to a reference potential via an overall capacitor circuit.

摘要： Electrical devices are connected to a DC voltage power supply grid being connected to a power source and having a supply voltage. Protection devices protect the electrical devices against an unintentional overcurrent sensed by a sensor unit. The protection devices disconnect the electrical devices from the DC voltage power supply grid when an overcurrent is detected. A pulse circuit having a capacitor with a semiconductor switching element connected in series with the capacitor is connected to respective inputs of the protection devices and supplies an amount of electric charge when a voltage dip occurs, wherein the amount of supplied electric charge is determined based on the detected overcurrent and a predetermined time period.
