    Abstract: A device, system, and method is disclosed for improving safety of a power system. For example, a differential current may be detected using at least one sensor by temporarily enabling sampling of current flowing through one or more conductors. Additionally, current flow may be temporarily altered in order to sample current in a system. The measurements may be handled locally and/or remotely and appropriate actions may be taken to enhance the overall safety of the system.

    Abstract: A method of signaling between a photovoltaic module and an inverter module. The inverter module is connected to the photovoltaic module. In an initial mode of operation an initial code is modulated thereby producing an initial signal. The initial signal is transmitted from the inverter module to the photovoltaic module. The initial signal is received by the photovoltaic module. The operating mode is then changed to a normal mode of power conversion, and during the normal mode of operation a control signal is transmitted from the inverter to the photovoltaic module. A control code is demodulated and received from the control signal. The control code is compared with the initial code producing a comparison. The control command of the control signal is validated as a valid control command from the inverter module with the control command only acted upon when the comparison is a positive comparison.

    Abstract: A system includes a central controller for determining at least one parameter for a load connector of a load. The system also includes a central transceiver for transmitting a signal relating to the least one parameter of the load connector. The load connector comprises input terminals for connecting to power lines of a power distribution network, output terminals for connecting to the load, a switch for connecting/disconnecting the input terminals to/from the output terminals, a connector transceiver for receiving the signal, a voltage sensor for measuring a voltage across the input terminals, and a connector controller. The connector controller may determine a voltage disconnect threshold for the load connector based on the at least one parameter. The connector controller may control the switch to connect the output terminals to the input terminals based on a voltage measurement and the voltage disconnect threshold.

    Abstract: Systems, apparatuses, and methods are described for power conversion. The power conversion may be done by a plurality of power devices with different configurations. For example, the plurality of power devices may include one or more converters with an upside-up buck configuration and one or more converters with an upside-down buck configuration. The power conversion may be done by one or more power devices that may be configurable between different modes of configuration. For example, one or more power converters may be configured in either an upside-up buck configuration mode or an upside-down buck configuration mode. The selection of a certain mode of configuration of the converter may be permanent or non-permanent.

    Abstract: A power harvesting system including multiple parallel-connected photovoltaic strings, each photovoltaic string includes a series-connection of photovoltaic panels. Multiple voltage-compensation circuits may be connected in series respectively with the photovoltaic strings. The voltage-compensation circuits may be configured to provide respective compensation voltages to the photovoltaic strings to maximize power harvested from the photovoltaic strings. The voltage-compensation circuits may be include respective inputs which may be connected to a source of power and respective outputs which may be connected in series with the photovoltaic strings.
