    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: 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: 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: 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: Stabilized power generation apparatus and techniques are disclosed. A stabilized power generator includes a power generating component (302), an energy store (330), a bi-directional Direct Current (DC) / DC converter (320), and a bi-directional DC / Alternating Current (AC) converter (316). The bi-directional DC/DC converter (320) is electrically coupled between the power generating component (302) and the energy store (330). The bi-directional DC/AC converter (316) is electrically coupled at a DC side of the bi-directional DC/AC converter to a circuit path between the power generating component (302) and the bidirectional DC/DC converter (320), and is to be electrically coupled at an AC side of the bi-directional DC/AC converter to an electrical grid (V_GRID, 340, 342). Distributed storage is thereby provided at each power generator, and the converters are controllable to provide MPP tracking in PV systems, power smoothing, and/or maintenance of State of Charge (SoC) of the energy store.
