摘要： An apparatus and method for protection in power installations are disclosed. The apparatus includes a power converter (505,605) configured to convert input power to direct-current output power on a power converter output terminal, the power converter comprising a controller (306) and a receiver (507, 607). The receiver provides an enable signal to the controller in response to a presence of a varying signal superimposed on the power converter output terminal. The controller shuts down the conversion of the input power to the direct-current output power if the power converter does not receive the enabling signal from the receiver.

摘要： A method for testing a photovoltaic panel ( 10 ) connected to an electronic module ( 12 ). The electronic module ( 12 ) includes an input attached to the photovoltaic panel and a power output. The method activates a bypass, by switch 50, to the electronic module ( 12 ). The bypass provides a low impedance path between the input and the output of the electronic module ( 12 ). A current is injected into the electronic module thereby compensating for the presence of the electronic module during the testing. The current may be previously determined by measuring a circuit parameter of the electronic module. The circuit parameter may be impedance, inductance, resistance or capacitance.

摘要： A device having a switch with a voltage applied across the switch. A current sensing circuit is connected to one terminal of the switch. The current sensing circuit receives power independently of the voltage applied across the switch. The power supply shares the other terminal of the switch with the current sensing circuit. The switch is adapted for opening and closing. When the switch closes, the current sensing circuit senses current through the switch and upon opening the switch the high voltage of the switch is blocked from the current sensing circuit. The sense current is caused to flow from the current sensing circuit to the other terminal when the switch is closed. The flow of the sense current produces a voltage which is compared differentially to another voltage referenced by the other terminal

摘要： A photovoltaic system including a photovoltaic cell, and an electronic module connected to the photovoltaic cell. The electronic module is adapted to produce at least one control signal indicative of electrical power being generated by the photovoltaic cells. A tracking controller is adapted to receive the control signal(s) and based on the control signal(s), the controller is adapted to control a tracking motor for adjusting the system so that electrical power generated by the photovoltaic cells is increased. The photovoltaic system may include an optical element, adapted for concentrating solar light onto the photovoltaic cells. The electronic module preferably performs direct current (DC) to direct current (DC) power conversion and maximum power point tracking by electrical power, current, or voltage at either their inputs or their outputs. Alternatively, the tracking controller is configured to also perform maximum power point tracking by increasing to a local maximum electrical power by varying at least one of (i) current or voltage output from the photovoltaic cell or (ii) current or voltage output from the electronic module.
