  • Patent number: 10777997
    Abstract: A method for operating an electronic circuit breaker having a semiconductor switch that is connected between a voltage input and a load output and that is driven as a function of the output voltage sensed at the load output during the switching on and/or cutting in of a capacitive load, wherein the output voltage is compared with a stored voltage threshold value, wherein when the voltage threshold value is reached or negatively exceeded, a current limit, to which a load current carried by the semiconductor switch is limited, is increased from a nominal value to a first step value increased therefrom, wherein the current limit is reduced stepwise from the first step value to the original nominal value, and wherein the semiconductor switch is opened if the output voltage does not reach the voltage threshold during a triggering time after the stepwise reduction of the current limit.

  • Publication number: 20200177003
    Abstract: A method for detecting arc faults when charging electric battery systems or lead acid batteries, which are electrically connected in series to form a string which is supplied via a DC voltage converter. A first value corresponding to an electric voltage applied to the string and a second value corresponding to an electric current flowing through the string are generated. As a first condition, it is checked whether the first value changes by more than a first limit value within a first time window. As the second condition, it is checked whether the second value changes by more than a second limit value within a second time window. An arc is detected if the first condition and the second condition are met within a third time window. Provided also is a method for manufacturing electric battery systems, in particular lead acid batteries, as well as to a cut-off device.

  • Patent number: 10637457
    Abstract: A method for controlling an electronic semiconductor switch connected in a load current circuit, the semiconductor switch being connected between an input terminal routed to a source and an output terminal of the load current circuit routed to a load. A control circuit is connected to a supply voltage and has a bridge circuit connected on the primary side to a transformer and to the supply voltage. A load circuit is connected to the transformer on the secondary side, the load circuit having a driver circuit for the semiconductor switch. A threshold value signal is routed to the bridge circuit on the control side.
