    Abstract: 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.

    Abstract: A converter circuit providing multiple current bypass routes between the output leads to provide reliability in a series connection of several converters. If the converter malfunctions due to component failure, the current bypass routes provide a path for the current that views the malfunctioning converter as substantially a short. Diodes prevent backflow into the power source connected to the converter. Redundancy is provided in the bypass portions of the converter circuit that provides alternate parallel paths in case a defective component in one of the paths opens the circuit along that path. In one example, the converter is implemented as a buck plus boost converter where either the buck or the boost portion or both are operative responsive to a controller controlling the switches of both portions. Most of the converter circuit may be implemented in an integrated circuit.

    Abstract: A method for theft detection in a system for generation of electrical power, the system including a DC power line. An alternating current (AC) is applied to the DC power line from an alternating current (AC) source and an impedance component of the system is sensed. The impedance is responsive to the applied alternating current (AC). An impedance datum proportional to the impedance is stored with the impedance datum transmitted to a receiver. Electrical charge may be stored to power the sensing when the system is not generating electrical power. The sensing includes measuring voltage and current of the alternating current (AC) source. A potential theft of a component of the system is alerted which is responsive to a change in the impedance greater than a previously determined threshold or upon not receiving an expected transmission of the impedance datum.
