摘要： A method for maintaining reliability of a distributed power system including a power converter having input terminals and output terminals. Input power is received at the input terminals. The input power is converted to an output power at the output terminals. A temperature is measured in or in the environment of the power converter. A temperature signal is input responsive to the temperature. The power conversion is controlled by adjusting the input power based on the temperature signal. The power conversion of the input power to the output power may be controlled to maximize the input power by setting at the input terminals the input voltage or the input current according to predetermined criteria. One of the predetermined criteria is configured to reduce the input power based on the temperature signal responsive to the temperature. The adjustment of input power reduces the input voltage and/or input current thereby lowering the temperature of the power converter.

摘要： 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.

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.

摘要： A monitoring system and method for monitoring performance of individual powers sources in a distributed power source system. A monitoring module is coupled to each of the power sources, or to each string of serially connected power sources, to monitor and collect data regarding current, voltage, temperature and other environmental factors at the power source. The collected data is transmitted over a power line to a central analysis station for analysis. Data collected from each source indicates malfunction or degradation at the source. Comparison of data collected from adjacent sources filters for environmental factors impacting neighboring sources such as cloudy days for a solar panel. Comparison of data collected from the same source at different times indicates soiling or degradation of the source with time or periodic events such as a moving shade from an adjacent building.

摘要： A system and method for combining power from DC power sources. Each power source is coupled to a converter. Each converter converts input power to output power by monitoring and maintaining the input power at a maximum power point. Substantially all input power is converted to the output power, and the controlling is performed by allowing output voltage of the converter to vary. The converters are coupled in series. An inverter is connected in parallel with the series connection of the converters and inverts a DC input to the inverter from the converters into an AC output. The inverter maintains the voltage at the inverter input at a desirable voltage by varying the amount of the series current drawn from the converters. The series current and the output power of the converters, determine the output voltage at each converter.
