A method and apparatus for converting DC input power to AC output power. The apparatus comprises means for storing energy from a DC input current, means for converting the DC input current to AC output current, means for causing the energy to be stored in and drawn from the means for storing during at least one storage and at least one burst period, respectively, the AC output current greater than the DC input current during the at least one burst period; a first means for determining a maximum power point (MPP) and operating the means for converting proximate the MPP; and a second means for determining a difference in a first and a second power measurement, producing an error signal indicative of the difference, and coupling the error signal to the first means to adjust at least one operating parameter of the means for converting to drive toward the MPP. |
