  • Patent number: 11299114
    Abstract: Disclosed is a motor vehicle electrical architecture comprising a supply switched by a relay. The architecture comprises a controllable resistive load (60) ensuring a consumption of, for example at least 500 mA, connected at the output of said relay and controlled by a computer (30) according to a control law. The controlled resistive load is only activated when the speed of said vehicle is zero, or very close to 0. This makes it possible to limit the duration of supply of the resistive load, and consequently the heat dissipation, electrical consumption and CO2 emissions over the duration of travel, while ensuring consumption at the switched supply voltage in the phases where the driver is likely to cut the ignition and thus cause the relay to open.

    Abstract: In an electrical distribution system including a solid-state circuit breaker (SSCB) and one or more downstream mechanical circuit breakers (CBs), a solid-state switching device in the SSCB is repeatedly switched ON and OFF during a short circuit event, to reduce a root-mean-square (RMS) value of the short circuit current. The resulting pulsed short circuit current is regulated in a hysteresis control loop, to limit the RMS to a value low enough to prevent the SSCB from tripping prematurely but high enough to allow one of the downstream mechanical CBs to trip and isolate the short circuit. Pulsing is allowed to continue for a maximum short circuit pulsing time. Only if none of the downstream mechanical CBs is able to trip to isolate the short circuit within the maximum short circuit pulsing time is the SSCB allowed to trip.

  • Patent number: 10096990
    Abstract: A surge voltage protection apparatus includes a surge voltage absorbing component, a ground component, an electrical status sensing circuit and a control unit. The surge voltage absorbing component receives a surge voltage, so that the electrical status sensing circuit senses an electrical status between the surge voltage absorbing component and the ground component to obtain an electrical data. The electrical status sensing circuit sends the electrical data to the control unit. After the control unit receives the electrical data, the control unit determines the electrical data. When the electrical data is greater than an electrical data predetermined value, the control unit informs a power supply apparatus that the electrical data is greater than the electrical data predetermined value, so that the power supply apparatus is turned off to protect the power supply apparatus.
