A method for controlling a switching circuit including an input port electrically coupled to a photovoltaic device and an output port electrically coupled to a load includes (1) entering a voltage limiting operating mode and (2) in the voltage limiting operating mode (i) causing a control switching device of the switching circuit to repeatedly switch between its conductive and non-conductive states in a manner which limits magnitude of an output voltage to a maximum voltage value, the output voltage being a voltage across the output port, and (ii) varying the maximum voltage value as a function of magnitude of an output current, the output current being a current flowing through the output port.

Switching circuits having multiple operating modes and associated methods

A maximum power point tracking controller includes an input port for electrically coupling to an electric power source, an output port for electrically coupling to a load, a control switching device, and a control subsystem. The control switching device is adapted to repeatedly switch between its conductive and non-conductive states to transfer power from the input port to the output port. The control subsystem is adapted to control switching of the control switching device to regulate a voltage across the input port, based at least in part on a signal representing current flowing out of the output port, to maximize a signal representing power out of the output port.
