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： 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 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 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： A PhotoVoltaic (PV) panel switching arrangement includes a first switch and a second switch, which in some embodiments are in a DC converter. The first switch is to be coupled between a power system and a first end of a circuit path of the PV panel, and 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. The switches are controlled for DC conversion of PV panel output where the circuit path of the PV panel is not to be bypassed, and to disconnect the first end of the circuit path from the power system and to close a bypass circuit path that bypasses the circuit path on a determination that the circuit path of the PV panel is to be bypassed.

摘要： Intelligent safety disconnect switching methods and arrangements for PhotoVoltaic (PV) panels are disclosed. A determination is made as to whether a reconnect condition, for reconnecting a PV panel to a power system from which the PV panel is disconnected, is satisfied. The PV panel is automatically reconnected to the power system responsive to determining that the reconnect condition is satisfied. A determination is then made as to whether a power system operating condition is satisfied on reconnection of the PV panel, and the PV panel is automatically disconnected from the power system responsive to determining that the power system operating condition is not satisfied on reconnection of the PV panel.

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.
