  • Publication number: 20220166206
    Abstract: A circuit breaker device is for coupling a DC voltage branch to a positive and a negative conductor on a DC voltage bus. In an embodiment, the circuit breaker device includes a series circuit including a safety fuse and a unidirectional switch module. The switch module has a parallel circuit includes a controllable semiconductor switch element that is conductive in a first current direction and a diode that is conductive in the opposite current direction.

  • Publication number: 20220149727
    Abstract: A switching device is for coupling a DC voltage branch to a DC voltage bus. The switching device includes a series circuit including a first switching module and a second switching module. A first diode is connected in parallel with the first semiconductor switching element and a second diode is connected in parallel with the second semiconductor switching element. A third semiconductor switching element is connected in parallel with the series circuit. A control device is connected to the first and second semiconductor switching elements, to the bridging semiconductor switching element, to the voltage sensor and to the current sensor. The control device is configured to, upon a first threshold value of the voltage being undershot and current flowing in an exceptional case, switch the bridging semiconductor switching element to the conducting state in order to facilitate a current flow from the DC voltage branch to the DC voltage bus.

  • Publication number: 20220130628
    Abstract: A DC voltage switch includes a first switch arranged at a first potential between a first terminal of the first switch and a second terminal of the first switch, a first discharging device which is arranged between the first terminal at the first potential and a third terminal at a second potential and includes a first switching element designed as a thyristor, and a second discharging device which is arranged between the second terminal and a fourth terminal at the second potential and includes a second switching element designed as a semiconductor switch that can be switched off. The respective discharging devices connect the first terminal and the third terminal and/or the second terminal and the fourth terminal, at least temporarily, when the DC voltage switch is being or has been switched off.

  • Publication number: 20220045672
    Abstract: An electronic switch has a first, a second and a third connection and is configured to disconnect a current flow between the first and the second connection. An energy source is connected between the first and the third connection, and a regenerative load is connected between the second and the third connection. The electronic switch includes a semiconductor switch capable of switching currents of different polarity. A fuse is connected between the first connection and the semiconductor switch. A first short-circuiter is connected between the input of the semiconductor switch and the third connection, and a second short-circuiter is connected between the output of the semiconductor switch and the third connection. The fuse has a current trigger threshold between a permanently permitted current and a maximally permitted current of the semiconductor switch. An electrical network having such electronic switch and a method for operating an electronic switch are disclosed.
