1. A method for operating a maximum power point tracking (MPPT) controller including a switching circuit adapted to transfer power between an input port and an output port, comprising the steps of:

  • in a first operating mode of the MPPT controller, causing a first switching device of the switching circuit to operate at a fixed duty cycle; and

    in a second operating mode of the MPPT controller, causing a control switching device of the switching circuit to repeatedly switch between its conductive and non-conductive states to maximize an amount of power extracted from a photovoltaic device electrically coupled to the input port.
