METHOD AND APPARATUS FOR MAXIMUM POWER POINT TRACKING FOR MULTI-INPUT POWER CONVERTER

摘要

A method and apparatus for maximum power point tracking (MPPT). In one embodiment, the method comprises (i) modulating an operating voltage of a first DC source by a first perturbation function to generate a first output power; (ii) modulating an operating voltage of a second DC source by a second perturbation function to generate a second output power, wherein the first and the second perturbation functions are synchronized with one another and out of phase with one another; (iii) comparing the first and the second output powers; and (iv) adjusting MPPT set points for both the first and the second DC sources in the same direction based on a result of comparing the first and the second output powers.
