  • Patent number: 10830808
    Abstract: An apparatus and method for detecting arc faults in a circuit having a switch (28), including a leakage current management device (46), an arc fault detector (30) arranged to monitor output voltage and to send a signal representative of the output voltage, and a controller (36) coupled to the arc fault detector (30). The controller (36) is configured to monitor the output voltage signal, compare the output to a threshold, and if the output exceeds the threshold, provide an arc fault indication.

  • Patent number: 10701798
    Abstract: Systems and apparatuses for electrically switching current include a first conductor formed of an electrically conductive material and having a first longitudinal axis; a second conductor formed of the electrically conductive material and having a second longitudinal axis; a set of switching components, each component selectively configured to electrically couple the first conductor to the second conductor; and a printed circuit board on which the first and second conductors are disposed. The width of the first conductor along the first longitudinal axis varies such that the current density in the first conductor is substantially constant along the first longitudinal axis and the width of the second conductor along the second longitudinal axis varies such that the current density in the second conductor is substantially constant along the second longitudinal axis.

  • Patent number: 10498130
    Abstract: Method(s) for limiting current in an electrical circuit having transmission wires for power transmission include determining whether an unexpected operating condition exists along the transmission wires and limiting the current to prevent (damage caused by) the unexpected operating condition. The method may further include disabling the electrical circuit if the unexpected operating condition persists. Additionally, a system includes a power source, a solid state power controller (SSPC) configured to operate in a first conducting state and a second non-conducing state, and a controller.
