Abstract

This paper proposes a new maximum efficiency point tracking (MEPT) technique that will achieve the highest efficiency for DC-DC converters by automatically tracking converter efficiency while changing the switching frequency and dead-time control parameters. This new technique helps identify optimal values of each parameter at different power levels. In this paper, the developed MEPT technique is theoretically analyzed and practically verified. The experiment is set up based on a 120W Cascaded Buck-Boost converter, controlled by a centralized digital-signal processor (DSP). It will be shown that the expected theoretical and experimental results are in close agreement with each other.
