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： 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： Photovoltaic system maximum power point tracking methods and apparatus are disclosed. Output power samples from one or more photovoltaic (PV) cells are obtained. The output power samples include perturbed samples for which a perturbation is applied to an operating voltage or current of the PV cell(s) and non-perturbed samples for which no perturbation is applied to the operating voltage or current. A control output, to change the operating voltage or current of the PV cell(s) for a next perturbed sample by a next perturbation, is generated. The next perturbation could be based on an estimated change in output power due to a previous perturbation. The next perturbation could also or instead be in a direction based on a change in output power samples, and of a magnitude based on the direction and a direction of perturbations applied for one or more perturbed samples preceding the next perturbed sample.

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： 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： An electrical power source includes a power converter and either an electrical generator or an electrical energy storage device. Power flow is controlled through controlling power converter based on a voltage source and resistance model of the electrical power source. A power converter for an electrical generator is controlled to synthesize or produce a constant voltage of the voltage source and a variable value of the resistance. The resistance value is controlled to deliver a maximum available output power to the electrical microgrid over a range of microgrid voltages up to a voltage below a maximum allowable voltage of the electrical microgrid. For an electrical energy storage device, the power converter is controlled to synthesize or produce a resistance value of the resistance that is dependent upon a phase angle between the voltage at the microgrid side of the electrical power source and current of the electrical energy storage device.
