摘要： Inverter internal communication features are disclosed. A multiple-stage inverter includes DC to DC and DC to AC converter switches in different power domains, which share no common return path connection. Operating parameters for converter switches in both power domains are determined by a single controller, located in one of the power domains. Converter control signals are communicated from the controller across an interface between the power domains. Respective, separate controllers in each power domain are not required. Components on each side of the interface could be integrated into respective integrated circuits. A planar transformer implemented in wiring levels of a Printed Circuit Board (PCB) that carries components of the inverter could be provided to enable communications between the power domains while reducing component count and physical space requirements.

摘要： A gateway controller allows a plurality of individual power generation units coupled to an electrical distribution grid to be controlled in a coordinated fashion. The gateway controller allows control of the plurality of individual power generation units as a single power generation unit. The gateway controller may determine required control parameters of the power generation units that will provide a desired combined behavior, such as combined alternating current injected into the grid, and issues commands to the power generation units based on the determined control parameters.

摘要： A PhotoVoltaic (PV) panel bypass switching arrangement includes first and second switches. The first switch is to be coupled between a power system and a first end of a circuit path of the PV panel in which a PV cells are connected, and is controllable to connect the first end of the circuit path to a power system and to disconnect the first end of the circuit path from the power system. The second switch is to be coupled between (i) a point between the first switch and the power system and (ii) a point between a second end of the circuit path and the power system, and is controllable to open and close a bypass circuit path that bypasses the circuit path. The first and second switches are controlled based on a determination as to whether the circuit path of the PV panel is to be bypassed.

摘要： An inverter having extended lifetime DC-link capacitors for use with a DC power source such as a photovoltaic panel is described. The inverter uses a plurality of switchable capacitors to control the voltage across the capacitors. The expected lifetime of the capacitors can be extended by disconnecting unnecessary capacitors from a voltage. The capacitors may be periodically connected to a voltage in order to maintain an oxide dielectric layer of the capacitor.

摘要： Power generating component connectivity testing methods and apparatus are disclosed. At a power generating component, a connectivity testing condition is detected. A connectivity testing procedure is performed on detection of the connectivity testing condition, to test connectivity in a system that includes the power generating component and an unpowered electrical system. Connectivity is tested before the electrical system is connected to a power grid. An indication of connectivity can be provided by receiving connectivity information indicating connectivity between power generating components and the unpowered electrical system; and providing a representation of the connectivity between the power generating testing procedure components and the electrical system. This representation could include, for example, one or more of: a connectivity alert, a visual representation of the power generating components; and a visual representation of the electrical system.

摘要： Intelligent safety disconnect switching methods and arrangements for PhotoVoltaic (PV) panels are disclosed. A switching device that is connected between a PV panel and a PV panel string detects a low current condition or an arc fault condition in the PV panel string. The switching device is automatically controlled to disconnect the
PV panel from the PV panel string responsive to detection of the low current condition or the arc fault condition. Switching device control could also be responsive to a disconnect command. For example, such a command could be generated by a grid sensor responsive to determining that an inverter, to which the PV panel string is connected, is not connected to an electrical grid.-

摘要： In event-based switching for power conversion, binary electrical event signals are selected from a number of available binary electrical event signals. Fewer than all of the available binary electrical event signals are selected. The selected binary electrical event signals are optionally processed in generating respective processed binary electrical event signals. One of the respective processed binary event signals is selected as a switch turn-on signal and another of the respective processed binary electrical event signals is selected as a switch turn-off signal, to control at least one switch in a switching mode power converter.

摘要： Photovoltaic power system inverter detection apparatus and methods are disclosed. Electrical continuity between an inverter in a PV power system and a PV panel disconnect switch, which switchably couples one or more DC PV panels to the PV power system, is tested while the PV panel disconnect switch is open. A state of the electrical continuity is determined based on measurements of an electrical parameter after the test signal is applied. The PV panel disconnect switch is maintained open on determining no electrical continuity, and closed on determining that there is electrical continuity between the PV panel disconnect switch and the inverter. A shutdown device that implements inverter detection may be located and/or adapted to meet safety conditions, by being located less than 10 feet from the PV panel array and/or adapted to limit a test signal to a maximum of 30V and 240VA.
