摘要： Power converter communications, including power converter communication methods and power converters that can communicate information, are disclosed. A control variable of a power converter is modulated, to modulate an output of the power converter for communicating information. Modulation of voltage or current on a circuit path to which the power converter is coupled could be detected, by another power converter, for example. Such modulation could be detected by sensors that are also used in controlling the power converter. Either or both of transmission and reception could therefore be provided without requiring any additional hardware at a power converter.

摘要： A first switch for connection in a first circuit path between a PV panel string and an inverter in a power system, and a second switch for connection in a second circuit path across an output of the PV panel string, are normally closed and open, respectively, during non-fault operation of the power system. Both series and parallel arc faults in the power system can be extinguished by further control of the switches. Arc fault detection could be based on probabilistic frequency analysis of current or power flow measurements in the PV panel string, current or power imbalance, interruption in communications with the PV panels, or combinations of these techniques.

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.

摘要： One or more first switches coupled to one of a primary transformer winding and a secondary transformer winding are controlled based on a first switch control reference clock signal. A reflected voltage across the other of the primary and secondary windings is sensed, and a second switch control reference clock signal is synchronized to the first switch control reference clock signal based on the reflected voltage. One or more second switches coupled to the other of the primary and secondary windings are controlled based on the second switch control reference clock signal. A digital isolator could instead be used to transfer a switch control reference signal across an isolation boundary. Switch control signals for controlling a set of switches on one side of the isolation boundary may be derived from a switch control reference signal that is synchronized with the transferred switch control reference clock signal.

摘要： Forward boost power converters, and related methods, are disclosed. In a switching mode power converter coupled between a first terminal pair and a second terminal pair, a first inductance is coupled to a first switch in a first circuit path across the first terminal pair. A capacitance is coupled to a second inductance in a second circuit path, and to the first inductance in a third circuit path. During their respective conduction periods, the first switch couples the first inductance across the first terminal pair, a second switch completes a circuit between the second terminal pair and one of: the second circuit path or the third circuit path, and a third switch completes the other of: the second circuit path and the third circuit path. Energy transfer involves both substantially linearly varying currents and substantially half sinusoidal current pulses.

摘要： A Galvanically Isolated Amplifier (GIA) includes an isolation barrier to galvanically isolate high voltage circuitry from low voltage circuitry. The high voltage circuitry has at least two voltage supply rails, with the voltage supply rail closest to ground potential at a first potential relative to the ground potential. The low voltage circuitry has at least two voltage supply rails, with the voltage supply rail closest to the ground potential at a second potential, the second potential being smaller than the first potential. A Radio Frequency (RF) carrier is digitally Phase Shift Keying (PSK) modulated for transmission across the isolation barrier. The unmodulated RF carrier could also be transmitted across the isolation barrier. PSK modulation could be applied to the RF carrier based on a test waveform to generate a PSK-modulated test signal for transmission while a voltage transient is applied between the high voltage circuitry and the low voltage circuitry.

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 thePV 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.

Each power domain includes an intelligent distribution panel, and the power domains are coupled to the power cables through the intelligent distribution panels. An intelligent distribution panel includes sockets, an internal power bus coupled to the sockets, and a controller.
