摘要
A method and apparatus for converting DC input power to AC output power. The apparatus comprises a conversion module comprising an input capacitor, and a first feedback loop for determining a maximum power point (MPP) and operating the conversion module proximate the MPP. The apparatus additionally comprises a second feedback loop for determining a difference in energy storage and delivery by the input capacitor, producing an error signal indicative of the difference, and coupling the error signal to the first feedback loop to adjust at least one operating parameter of the conversion module to drive toward the MPP.
