Abstract
This paper proposes the design of the Average Current-mode Control loop applied to parallel converters by means of H∞ Control Theory. The sensitivity to low-frequency disturbances of the converter can be drastically reduced by applying H∞ control techniques, preserving the loop stability with respect to high frequency uncertainties of the linear model. The analytical study is validated by experimental measurements carried out on a 5V-20A, 50kHz parallel-module converter composed by four buck DC-DC power stages.
