<p>A method for performing maximum power point tracking (MPPT) in a photovoltaic inverter system includes sampling (310) a present value of a current I and a present value of a voltage V from a solar photovoltaic (PV) panel, determining (312) a first step, a second step, and a third step from the present current value and the present voltage value, and setting a present reference voltage to a previous reference voltage (318, 328), if the present voltage value equals a previous voltage value (314) and the present current value equals a previous current value (316), or if the present voltage value does not equal the previous voltage value (314) and a current-voltage derivative equals a current-voltage ratio (326).</p> |
