    摘要： In a solar panel array, each solar panel in a series-connected string has a current source connected across its output terminals. The current source generates a programmable output current equal to the difference of the load current drawn from the panel and the current corresponding to the maximum power point (MPP) of the panel. As a result, each of the panels in the string is operated at its MPP. When the array contains multiple strings connected in parallel, a voltage source is additionally connected in series with each string. The voltage sources are programmable to generate corresponding output voltages to enable operation of each panel in each of the multiple strings at its MPP. Respective control blocks providing the current sources and voltage sources automatically determine the MPP of the corresponding panels. In an embodiment, the control blocks are implemented as DC-DC converters in conjunction with measurement and communication units.

    摘要： In a solar panel array that includes a string of series-connected panels, the load current flowing through the string is measured. The peak current (Ipp) of a panel in the string is determined. A current equal to the difference of the load current and the peak current (Ipp) is generated in a current source connected across the output terminals of the panel. The panel is thereby operated at its maximum power point (MPP). To determine the peak current (Ipp) of the panel, the magnitude of current flowing through the panel is iteratively changed and the corresponding power generated by the panel is computed. The change in the current through the panel and the measurement of the corresponding power are repeated until a maximum power is determined as being generated by the panel. The maximum power corresponds to the maximum power point (MPP) and the peak current (Ipp) of the panel.
