Variable- Step-Size Auto-Tuning Algorithm For Digital Power Converter With Variable-Switching-Frequency

Abstract

This paper presents the analysis and implementation of a digital controller with adaptive autotuning algorithm that has a variable step size to track and detect the optimum switching frequency for a DC-DC converter. The algorithm is theoretically analyzed and developed based on buck DC-DC converter loss model and behavior and directed towered improving the convergence speed and accuracy of the adaptive loop by adjusting the converter switching frequency with variable step size. Simulation results are presented for the developed algorithm under variable conditions. Future experimental work is also discussed. © 2007 IEEE.
