摘要： 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.

摘要： A multiplicity of uninterruptible power supply (UPS) devices may be equipped with a plurality of sensors which report on the state of various operational parameters of the UPS devices to a registry device. Output of the registry device may be displayed on a dedicated GUI and/or written to log files at a monitoring station. In the event that one or more sensors reports a parameter to the registry device which is indicative of a malfunction of one or more of the UPS devices, examination the registry device output may indicate which UPS device or devices is/are malfunctioning. Related embodiments, apparatus, systems, and methods are also discussed.

摘要： One or more systems and methods for providing selective isolation between a grid and an electric vehicle (EV) during charging are disclosed. An isolation component may be located between input nodes, and one or more output nodes. The isolation component may be connected to the nodes by switches that select which one or more nodes is used to supply power for charging the EV battery. Other switches, such as relays, may bypass the isolation component when the grid is not connected. Further switches may isolate part of the system from the grid to connect the isolated power source to the EV, and in parallel connect the isolation component to the grid for combined power EV battery charging. The isolation component may comprise electrical energy storage devices with switches in series surrounding each device, where the switches may be operated in a break-before-make transition.

摘要： A method for arc detection in a system including a photovoltaic panel and a load connectible to the photovoltaic panel with a DC power line. The method measures power delivered to the load thereby producing a first measurement result of the power delivered to the load. Power produced by the photovoltaic panel is also measured, thereby producing a second measurement result of power produced by the photovoltaic panel. The first measurement result is compared with the second measurement result thereby producing a differential power measurement result. Upon the differential power measurement result being more than a threshold value, an alarm condition may also be set. The second measurement result may be modulated and transmitted over the DC power line.

摘要： A power converter employing a plurality of parallel high-frequency switching legs, and a low-frequency switching leg, is disclosed. A load may be coupled between the high-frequency switching legs and the low-frequency switching leg. A number of levels of a power waveform produced by the power converter may be higher than the number of levels of the high-frequency switching legs. The low-frequency switching leg may employ switches which may have low switching frequency characteristics, low conduction losses, and may be less expensive.

摘要： Controlling a power converter circuit for a direct current (DC) power source is disclosed. The power converter may be operative to convert input power received from the DC power source to an output power and to perform maximum power point tracking of the power source. The power converter is adapted to provide the output power to a load that also performs maximum power point tracking.
