Abstract: The disclosure discloses a driver circuit that is intended for a power semiconductor switch having a unidirectional flow direction and having a control connection, a reference potential connection and a controlled connection. The driver circuit includes a driver module having a control output, a reference potential input and an overvoltage monitoring input. In this case, the control output is connected to a first connection that is provided for connection to the control connection, the reference potential input is connected to a second connection that is provided for connection to the reference potential connection, and the overvoltage monitoring input is connected, via a first diode, to a third connection that is provided for connection to the controlled connection. The overvoltage monitoring input is also connected to the reference potential input via a capacitance. A connection path from the second connection to the third connection via the capacitance and the first diode is switchable in the driver circuit by means of an actively controllable switching element. Furthermore, the disclosure also discloses a circuit arrangement comprising such a driver circuit and a power semiconductor switch with a unidirectional flow direction as well as a bidirectional circuit arrangement comprising two subcircuit arrangements that are each formed by such a circuit arrangement. Such a bidirectional circuit arrangement is used in an inverter having a BSNPC bridge circuit.

Abstract: The disclosure relates to an integral inductor arrangement with at least three magnetic loops arranged side by side to each other in a row and at least one winding associated with each of the magnetic loops. The magnetic loops are formed by individual core elements, each of which being part of one of the magnetic loops, and shared core elements, each of which being part of two adjacent of the magnetic loops. The shared core elements are separated from the individual core elements by magnetic gaps and each of the at least one winding is arranged around one of the individual core elements. The disclosure further relates to a use of such integral inductor arrangement within a 3-phase AC-filter for a power inverter for feeding electrical power into a power grid.

Abstract: An inductor assembly is disclosed that includes a magnetic core with a center leg and a number n of phase legs, wherein n is an integer and n>1. Each phase leg is magnetically connected to the center leg by an upper bridge and a lower bridge to form a magnetic main loop, a midpoint of the phase leg being magnetically connected to a center point of the center leg by a shunt element comprising a gap. Each phase leg further includes an upper inductor coil disposed on an upper phase leg section located between the midpoint and the upper bridge and a lower inductor coil disposed on a lower phase leg section located between the midpoint and the lower bridge. Alternatively, the upper and lower inductor coils are disposed on respective upper and lower bridges.
