Abstract: A network unit may be operatively attached to power lines of an interconnected power system and/or a device such as a power module that may further include a communication interface. The network unit may be operable to superimpose a first signal representative of a sensed parameter of the power system onto the power lines, thereby to transmit the first signal to other power modules in the interconnected power system or to a power device in interconnected power system. The network unit may receive a second signal of the parameter superimposed onto the power lines from another network unit.

Abstract: A method for a power system having a string of a plurality of power sources connected across a power device includes connecting a plurality of safe voltage units having safety switches connected respectively across each of the power sources. The method includes sensing a plurality of parameters of the power sources, and monitoring for a signal transmitted from the power device. Each of the safety switches is activated to be OFF responsive to detecting the signal within a predetermined time period. Upon not detecting the signal from the power device within the predetermined time period, a safe mode of operation of the power system is entered in which the voltages of each of the power sources is reduced to a voltage level less than a predetermined voltage level by turning the safety switches ON.

Abstract: An apparatus comprising a signal transformer coupled to a power line and a signal transmission, reception, or detection circuit. A sensor is configured to be responsive to the power line current or magnetic flux generated in a ferrite core of the signal transformer. When the sensor indicates that the flux generated by the power line current mat cause an attenuation of the signal strength, a second circuit generates a current through a flux cancelling winding that cancels at least some of the flux generated by the power line current.

Abstract: A switching device has a cover including: a hollow content area housing a plurality of connectors; one or more openings designed to allow passage of one or more conductors; and one or more reflective agents mounted on the cover such that changing a physical location of an entirety of the cover with respect to an enclosure of an electronic device changes a location of the one or more reflective agents. A sensor is configured to sense the one or more reflective agents and output an electrical signal depending on the location of the sensed one or more reflective agents mounted on the cover. The sensor is positioned outside of the hollow content area of the cover. A controller is configured to change a state of the electronic device according to the output electrical signal of the sensor. The cover is mounted on an exterior surface of the enclosure.

Abstract: Methods for arc detection in a system including one or more photovoltaic generators, one or more photovoltaic power devices and a system power device and/or a load connectible to the photovoltaic generators and/or the photovoltaic power devices. The methods may measure voltage, current, and/or power delivered to the load or system power device, and the methods may measure voltage noise or current noise within the photovoltaic system. The methods may periodically, and/or in response to detecting noise, reduce an electrical parameter such as current or voltage in order to extinguish an arc. The methods may compare one or more measurements to one or more thresholds to detect arcing, and upon a comparison indicating that arcing is or was present, an alarm condition may be set.

Abstract: Various implementations described herein are directed to a methods and apparatuses for disconnecting, by a device, elements at certain parts of an electrical system. The method may include measuring operational parameters at certain locations within the system and/or receiving messages from control devices indicating a potentially unsafe condition, disconnecting and/or short-circuiting system elements in response, and reconnection the system elements when it is safe to do so. Certain embodiments relate to methods and apparatuses for providing operational power to safety switches during different modes of system operation.

Abstract: A method and apparatus to bypass, using bypass circuits, non-operating power modules in a power system. Multiple power sources are coupled to inputs of respective power modules. Multiple bypass circuits have respective terminals operatively coupled to the respective outputs of the power modules. The outputs of the power modules are coupled in a series connection and the series connection is coupled across a load. Each bypass circuit includes a switch operatively coupled across a first input of a circuit and an output of a power module. A feedback circuit includes a second input coupled to an output of the circuit. A coupling circuit includes a third input coupled to an output of the feedback circuit. The coupling circuit includes an output operatively coupled across the switch. The switch is biased to provide the bypass responsive to a voltage of the output of the circuit and the voltage of the power module output.
