Title

Maximum Efficiency Point Tracking (Mept) Method And Dead Time Control

Abstract

Adaptive control method, to be called Maximum Efficiency Point Tracking (MEPT), is presented in this paper. This method tracks the system efficiency, which is a DC-DC converter here, and optimizes adaptively system parameters to maximize the efficiency. MEPT method is used in this paper to optimize the primary-to-secondary switches dead time parameter in an isolated topology to prevent switches body diodes conduction during freewheeling periods and reduces body diodes conduction related losses in order to improve the efficiency. MEPT tracks the converter efficiency while changing the dead time and detects the optimized dead time value at the maximum efficiency point at different load and line conditions. In this paper, the MEPT method is discussed, analyzed, and digital control algorithm and implementation are presented.
