  • Method and apparatus for improving PV module fill factor using a voltage clamping circuit
    Patent number: 11146062
    Abstract: A method and apparatus for voltage clamping including: measuring a DC voltage across the PV module at an input of a power converter, comparing the measured DC voltage to the overvoltage threshold, determining the measured DC voltage exceeds the overvoltage threshold, and operating a clamping circuit to clamp at least a portion of the DC voltage prior to input to the power converter.
    Type: Grant
