    摘要： A photovoltaic inverter system and an operation method thereof are provided. The photovoltaic inverter system includes photovoltaic modules, DC/DC converters, at least one direct current combiner device and a centralized inverter. An input signal or an output signal of each of the DC/DC converters is sampled by the DC/DC converter, and a loop process is performed by the DC/DC converter on the input signal or the output signal to maintain the input signal or the output signal at a preset value, so as to keep the output power of the photovoltaic module to be the maximum output power, thereby solving the problem of the series-parallel mismatch of a photovoltaic array due to being shaded or aging of a photovoltaic module. In addition, the photovoltaic inverter system can include only one centralized inverter. Therefore, the cost is reduced compared with photovoltaic inverter systems in the conventional technology.

    摘要： A power harvesting system including multiple parallel-connected photovoltaic strings, each photovoltaic string includes a series-connection of photovoltaic panels. Multiple voltage-compensation circuits may be connected in series respectively with the photovoltaic strings. The voltage-compensation circuits may be configured to provide respective compensation voltages to the photovoltaic strings to maximize power harvested from the photovoltaic strings. The voltage-compensation circuits may be include respective inputs which may be connected to a source of power and respective outputs which may be connected in series with the photovoltaic strings.

    摘要： An apparatus formed with a plurality of power subsystems, and method of operating the same. In one embodiment, the apparatus is formed with plurality of local controllers to control an operating characteristic of at least one of the plurality of power subsystems. A central controller of the apparatus is configured to receive an indication of an overall power produced by the plurality of power subsystems, selectively command a first local controller of the plurality of local controllers to change a value of the operating characteristic of a first power subsystem of the plurality of power subsystems, receive an indication of a change in the overall power in response to the change in the value of the operating characteristic of the first power subsystem, and store, in memory, the change in the value of the operating characteristic of the first power subsystem if the overall power is increased.
