  • Driver circuit, circuit arrangement comprising a driver circuit, and inverter comprising a circuit arrangement
    Patent number: 10804791
    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.

  • Step-up converter, corresponding inverter and method of operation
    Patent number: 10491103
    Abstract: A step-up converter includes a first inductance electrically connecting a first DC voltage input of the step-up converter to a first junction point, a step-up converter switch connecting the first junction point to a second DC voltage input and a second DC voltage output of the step-up converter, a first diode connecting the first junction point to a first DC voltage output of the step-up converter, and a snubber circuit comprising a charging path and a discharging path. The discharging path runs as a series connection of a capacitor and a second diode from the first junction point to the first DC voltage output, and the charging path is connected at its one end to a junction point between the capacitor and the second diode and is arranged such that the capacitor is charged when the step-up converter switch is switched on.
